Answer:

x =42

q = 135°

p + q + r = 225°

Step-by-step explanation:

a)

Since, AB and BC are perpendicular lines.

[tex] m\angle ABC = 90\degree \\

\therefore 24\degree + x\degree + 24\degree = 90\degree \\

\therefore x\degree + 48\degree = 90\degree \\

\therefore x\degree = 90\degree - 48\degree \\

\huge \red {\boxed {\therefore x = 42}} \\[/tex]

b) (i)

Since, CD and EF are parallel lines and AB is a straight line.

[tex] \therefore q = 135\degree... (vertical \: \angle 's) \\\\

p + 135\degree = 180°..(straight\: line \: \angle' s) \\

p = 180\degree - 135\degree \\

\huge \purple {\boxed {p = 45\degree}} \\

\because r = p ... (vertical \: \angle 's) \\

\huge \purple {\boxed {r = 45\degree}} \\

p + q + r = 45\degree + 135\degree + 45\degree \\

\huge \purple {\boxed {p + q + r = 225\degree }}\\[/tex]

The correct options are m ∠ 1 = 50°, m ∠ 1 + m ∠ 2 + m ∠ 3 = 180° and 50+2x+x+25 = 180

Parallel lines can be defined as two lines in the same plane that are at equal distance from each other and never meet.

Given that, two parallel lines l and m are intersected by lines s and t. some angles are made by them, we need to select the correct options for them,

Correct options with reasons :-

∠ 1 = 50° is a true statement because they are vertically opposite angles.

m ∠ 1 + m ∠ 2 + m ∠ 3 = 180°, is a correct statement because they are interior angles of a triangle.

50+2x+x+25 = 180, is a correct answer because they are angles lying in a straight line.

Hence, the correct options are m ∠ 1 = 50°, m ∠ 1 + m ∠ 2 + m ∠ 3 = 180° and 50+2x+x+25 = 180

Answer:

3t+11

Step-by-step explanation:

A pentagon has 5 sides

Perimeter is the total measurement around an object=20t+7

we have not been given the 5th side measurement so lets make it x

6t +2t+4t-5+5t+1+x=20t+7

put the liketerm together i e

6t+2t+4t+5t-20t+x=7+5-1

-3t+x=11

x=11+3t.

So the measurements of the fifth side is 11+3t same as 3t+11

Answer:

Step-by-step explanation:

If you want to know what you have to multiply by 5 to get a product of 70, you would divide 70 by 5 to get that other number. Because 70 divided by 5 is 14, you know that the other number is 14. It's the same when you have one factor of a polynomial and want to know the other. You divide your polynomial by the one factor to get to the other factor, because when you multiply them together, you get back the polynomial you started with. Like when we found that 70 / 5 = 14, we know that when we multiply 14 by 5 we'll get the 70 we started with.

Long division of polynomials will be difficult to illustrate within this forum, but I'll do my best. What we want to do is divide [tex]6x^2+x-15[/tex] by 2x - 3:

          __________

2x - 3 | [tex]6x^2+x-15[/tex]

First divide the 6 x-squared by the 2x (forget about the rest of what's inside the box for now, and also forget about the -3 for now. We'll deal with them later).  2x goes into 6 x-squared 3x times, because 2x * 3x = 6x-squared, right? So the 3x goes above the 6x-squared:

           3x_______

2x - 3 | [tex]6x^2+x-15[/tex]

Now we multiply the 3x by the 2x and put that product under the 6x-squared. The product is 6x-squared (which will always be the case in division that they will subtract each other away. That's why we do this!)Then multiply the 3x by the -3 which is -9 and put that under the "+x" term:

           3x________

2x - 3 | [tex]6x^2+x-15[/tex]

           6x^2-9x        

At this point we change the signs and have

            3x                

2x - 3   | 6x^2 + x - 15

          -  6x^2 +9x

And then we add and bring down the -15:

           3x                  

2x - 3 | 6x^2  + x - 15

         - 6x^2 + 9x

                       10x - 15

Now do the division process again, this time dividing 10x by 2x (again the -3 will wait). 10x divided by 2x is 5 (because 2x * 5 = 10x, right?). The 5 goes above the +x on top:

           3x    +   5      

2x - 3 | 6x^2 +  x - 15

        -  6x^2 + 9x

                       10x - 15

Now we wwill multiply the 5 by both the 2x and the -3 and subtract:

           3x     +  5    

2x - 3 | 6x^2 +  x - 15

         - 6x^2 + 9x

                       10x - 15

                     - 10x + 15

Notice that when we subtracted, the 10x changed from + to -, and the -15 changed to a positive. The remainder is 0.

That tells us that the other factor of the polynomial is 3x + 5. You could also have done synthetic division, but it would be more difficult than this to illustrate because you would be dividing by 3/2.  :/  

Answer:

20. 13 cm

21. 12 cm

Step-by-step explanation:

20. isosceles means two sides are the same length, so you take the ten off the perimeter to get 26 remaining cm (36 -10) and you then divide that by two to get both sides of 13 cm (26 / 2)

21. because you know that if you split the triangle down the middle you get a right triangle and you can use a^2+b^2=c^2 to find the height, so we take the one side of 13 cm and half of the third side, which is 5, and you can find your answer (a^2 + 5^2 = 13^2   ---> a^2 + 25 = 169 ---> a^2 = 144 ---> a = 12)

Answer:

y< -1/3

Step-by-step explanation:

To solve the inequality, we must get the variable, y, by itself.

9y< -3

Perform the opposite of what is being done to the equation, to both sides.

y is being multiplied by 9. The opposite of multiplication is division. Therefore, divide both sides by 9.

9y/9 < -3/9

y< -3/9

-3/9 can be reduced. 3 can be divided evenly into both the numerator (top number) and denominator (bottom number).

y< (-3/3) / (9/3)

y< -1/3

Step-by-step explanation:

Think of the outside function as a scaling quantity. You are applying that outside term to each and every term on the inside, Thats the basis for the distributive property.

1.)3 x 2 + 3 x 8 = 24

Now that you got the steps down, ima do the rest in my head

2.) 2

3.) -10

4.) -50

Answer:

Step-by-step explanation:

Distributive property: a(b +c) = ab + ac

                                    a(b - c) = ab - ac

1) 3(2 + 8) = 3*2 + 3*8

                = 6 + 24

                = 30

2) (-3 + 4)2 = -3*2 + 4*2

                 = -6 + 8

                = 2

3) -5(4 - 2) = -5*4 - (-5)*2

                 = - 20 + 10

                = -10

4)(12 +13)(-2) = 12*(-2) + 13 *(-2)

                    = -24 - 26

                    = -50

Answer:

(f+4)(f−5)

Step-by-step explanation:

Factoring means we want something like

(f+_)(f+_)

We need two numbers that...

Add together to get -1

Multiply together to get -20

4+-5 = -1

4*-5 = -20

Fill in the blanks in

(f+_)(f+_)

with 4 and -5 to get...

(f+4)(f-5)

_______________________________

Hey!!

Solution,

f^2-f-20

= f^2-(5-4)f-20

= f^2-5f+4f-20

= f(f-5)+4(f-5)

=(f-5)(f+4)

So the answer is (f-5)(f+4)

Answer:

The dogs are 21. 8 m from each other in 5 seconds

Step-by-step explanation:

Given;

speed of Edison, v = 10 m/s

speed of Einstein, u = 8 m/s

angle between the two dogs, θ = 25°

let the distance ran by Edison in 5 seconds = x = (10 m/s x 5 s) = 50 m

let the distance ran by Einstein in 5 seconds = y = (8 m/s x 5 s) = 40 m

let the distance between the two dogs after 5 seconds = z

x , y and z forms a triangle with an angle between x and y as θ

The third side, z, can be calculated using cosine rule

z² = x² + y² - 2xyCosθ

z² = 50² + 40² - (2 x 50 x 40)Cos25

z² = 4100 - 4000Cos25

z² = 474.7689

z = √474.7689

z = 21.789 m ≅ 21. 8 m

Therefore, the dogs are 21. 8 m from each other in 5 seconds
