what’s the awnser for this???

Answer:

A = 19.1°

B = 95.5°

C = 65.4°

Step-by-step explanation:

B = 5A

C = 4A-11

We know that a triangle has a total of 180° so:

180 = A + B + C

Which can be written as:

180 = A + (5A) + (4A - 11)

180 = 10A - 11

10A = 191

A = 19.1°

With A, we can work out B and C:

B = 5(19.1)

B = 95.5°

C = 4(19.1) - 11

C = 76.4 - 11

C = 65.4°

Answer:

[tex]48.5cm^{2}[/tex]

Step-by-step explanation:

This shape is actually just a rectangle with a missing triangle. We can first find the area of the rectangle with [tex]7*8=56[/tex] and subtract the triangle.

Area of missing triangle = [tex]\frac{1}{2} *b*h[/tex] (b is the base and h is the height)

Base = [tex]8-3=5[/tex]

Height = [tex]7-4=3[/tex]

Area of missing triangle = [tex]\frac{1}{2} *5*3=7.5[/tex]

Area of the figure: [tex]56-7.5=48.5[/tex]

--------------------------------------------------------------------------

Alternatively, you can find the area of each individual shape and add them all up.

Area of the rectangle: [tex]8*4=32[/tex]

Area of square: [tex](7-4)*3=9[/tex]

Area of triangle: [tex]\frac{1}{2} *(8-3)*(7-4)=\frac{1}{2} *5*3=7.5[/tex]

Total Area: [tex]32+9+7.5=48.5[/tex]

Answer:

49.2

Step-by-step explanation:

I first found the area (length x Width) of the rectangle which is 8x4= 32

Then I subtracted 7cm and 4cm to find the width of the square which is 3cm

To find the area of the square multiple 3x3= 9

Then to find the area of the triangle I subtracted 8cm and 3cm to get the length of the triangle which is 5cm

You already know the width of the triangle (3cm) so you multiply 5cm x 3cm to get 15, but snice its a triangle you’re going to divide 15 by 2 = 7.2

Lastly your going to add up all those numbers :

32+9+7.2 = 49.2

So the area of the triangle is 49.2

Answer:

2x-4

Step-by-step explanation:

1) Since it says 2 times the number x, it is 2x

2) Then, it says 4 less than 28

3) The equation/answer would be 2x-4

Answer:

The answer is 2x-4

Answer:

I would find the area of the circle and then find the area of the shape in the middle and then minus that from the area of the whole circle

Answer:

Step-by-step explanation:

1. Find the area of the circle. Area_c = pi * r^2

2.Find the area of the pentagon in terms of the radius Area_P =

3 sqrt(3) r^2 / 2

The answer you want is Area_shade = Area_c - area_P

Area = pi * r^2 - 3 sqrt(3)r^2/2

Area = r^2 (pi - 3 sqrt(3)/2)

Answer:

[tex] \boxed{\sf d. \ \frac{a}{b} = \frac{10}{7}} [/tex]

Step-by-step explanation:

[tex] \sf \implies \dfrac{a - b}{b} = \dfrac{3}{7} \\ \\ \sf \implies \frac{a}{b} - \frac{b}{b} = \frac{3}{7} \\ \\ \sf \implies \frac{a}{b} - 1 = \frac{3}{7} \\ \\ \sf \implies \frac{a}{b} - 1 + 1 = \frac{3}{7} + 1 \\ \\ \sf \implies \frac{a}{b} = \frac{3}{7} + 1 \\ \\ \sf \implies \frac{a}{b} = \frac{3}{7} + \frac{7}{7} \\ \\ \sf \implies \frac{a}{b} = \frac{3 + 7}{7} \\ \\ \sf \implies \frac{a}{b} = \frac{10}{7} [/tex]

Answer:70

Step-by-step explanation:

Answer:

The slope of a line characterizes the direction of a line.

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. also You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

Hey there! I'm happy to help!

Let's flip the equation so x is on the left. We want to isolate x to see what it equals.

4x+3=-13

We subtract 3 from both sides.

4x=-16

We divide both sides by 4.

x=-4.

Have a wonderful day! :D

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = - 4}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ - 13 = 4x + 3}[/tex]

Swap the sides of the equation

[tex] \longrightarrow{ \sf{4x + 3 = - 13}}[/tex]

Move 3 to right hand side and change it's sign

[tex] \longrightarrow{ \sf{4x = - 13 - 3}}[/tex]

The negative integers are always added but posses the negative ( - ) sign

[tex] \longrightarrow{ \sf{4x = - 16}}[/tex]

Divide both sides by 4

[tex] \longrightarrow{ \sf{ \frac{4x}{4} = \frac{ - 16}{4}}} [/tex]

Calculate

[tex] \longrightarrow{ \sf{x = - 4}}[/tex]

Hope I helped!

Answer:

∠K =24

∠L =66

Step-by-step explanation:

first you need to find X in order to solve.

since they are Complementary they add together to equal 90 degrees

so we can set them equal to 90

13x-1=90

13x=91

x=7

now we can plug them in!

---

∠K = 3(7)+3 = 24

∠L =10(7)-4=66

Answer:

[tex]( \frac{3}{7 } \times \frac{ - 5}{8}) \div ( \frac{1}{3} \times \frac{5}{6}) + | \frac{ - 1}{2} - \frac{1}{5} | = - \frac{ - 15}{56} \div \frac{5}{18} + | - \frac{7}{10} | = \frac{ - 270}{280} + \frac{7}{10} = \frac{ - 270}{280} + \frac{196}{280} = \frac{ - 74}{280} = \frac{ - 37}{140} [/tex]
