Find The Area Of The Isosceles Triangle.13 Cm10 Cm

Answers

Answer 1

Answer:

Area of the triangle = 60 cm²

Step-by-step explanation:

Two equal sides of the given isosceles triangle measure 13 cm.

Third side of the triangle = 10 cm

Since, formula to get the area of a triangle with given three sides is given by,

Area = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Where a, b and c represent the sides of the triangle

And s = [tex]\frac{a+b+c}{2}[/tex]

For the given isosceles triangle,

s = [tex]\frac{13+10+13}{2}[/tex]

s = 18

(s - a) = (18 - 13) = 5 cm

(s - b) = (18 - 10) = 8 cm

(s - c) = (18 - 13) = 5 cm

Substituting these values in the formula,

Area of the triangle = [tex]\sqrt{18\times 5\times 8\times 5}[/tex]

                                 = [tex]\sqrt{3600}[/tex]

                                 = 60 cm²

Therefore, area of the given isosceles triangle is 60 square cm.

Answers

Answer:

Answer: B. 38 mm

Step-by-step explanation:

The Perimeter of a Shape

The perimeter of a given shape is the sum of all exterior lengths surrounding the shape.

The figure shows a shape where all the external measures are given except the leftmost side.

This length is the sum of 3 mm + 10 mm = 13 mm.

Now calculate the perimeter:

P = 4 mm + 3 mm + 10 mm + 8 mm + 13 mm = 38 mm

Answer: B. 38 mm

What do the equations have in common and how are they different

Answers

Answer:

Slope -intercept for of equation 1: [tex]y=-2x+5[/tex]

Slope -intercept for of equation 2: [tex]y=-2x+3[/tex]

Looking at slope-intercept form of both equations, we have slope m = -2

Both have same slopes so, the lines are parallel.

Step-by-step explanation:

We need to write equations in slope-intercept form.

The general formula of slope-intercept form is: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

The first equation is:

[tex]2x+y=5[/tex]

Slope-intercept form:

[tex]y=-2x+5[/tex]

The second equation is: [tex]3y=9-6x[/tex]

Rearranging: [tex]3y=-6x+9[/tex]

Slope-intercept form:

[tex]y=\frac{-6}{3} x +\frac{9}{3}\\y=-2x+3[/tex]

Slope -intercept for of equation 1: [tex]y=-2x+5[/tex]

Slope -intercept for of equation 2: [tex]y=-2x+3[/tex]

Looking at slope-intercept form of both equations, we have slope m = -2

Both have same slopes so, the lines are parallel.

They have different y-intercepts.

Answers

Answer:

x= -8

y=7

Step-by-step explanation:

make it so the x's cancel out

to do this multiply the bottom equation by 2

2x+3y=5

2x+4y=12

subtract to cancel out the x

-y=-7

y=7

now substitute y into one of the equations(I'm going to do x+2y=6)

x+2(7)=6

x+14=6

x=-8

Multiply the bottom equation by -2

2x + 3y = 5
-2x + -4y = -12
-y = -7
y = 7

x + 2(7) = 6
x + 14 = 6
x = 6 - 14
x = -8

x = -8, y = 7

Two complementary angles have measures of `s` and `t`. If `t` is 9 less than twice `s`, what are the measures of each angle?

The value of s and t.
with work explaining.

Answers

Answer:

s measures 33° and t measures 57°.

Step-by-step explanation:

Since the two angles s and t are complementary, this implies that:

[tex]m\angle s+m\angle t=90[/tex]

We are given that t is 9 less than twice s. Hence:

[tex]m\angle t=2m\angle s-9[/tex]

We can substitute this into the first equation:

[tex]m\angle s+(2m\angle s-9)=90[/tex]

Solve for s. Combine like terms:

[tex]3m\angle s-9=90[/tex]

Adding 9 to both sides yields:

[tex]3m\angle s=99[/tex]

And dividing both sides by 3 gives us that:

[tex]m\angle s=33^\circ[/tex]

Returning to our second equation, we have:

[tex]m\angle t=2m\angle s-9[/tex]

So:

[tex]m\angle t=2(33)-9=66-9=57^\circ[/tex]

So, s measures 33° and t measures 57°.

Answer:

Two complementary angles have measures of `s` and `t`.

Hence, s+t=90°

`t` is 9 less than twice `s`, t=2s-9

According to the above problem,

→s+t=90

→s+2s-9=90

→3s=99

→s=99/3

s=33

Therefore, the value of s=33°and t=2(33)-9 = 66-9 = 57°.

There are 178 more bikers than hikers if there are 676 people in the park total how many people are hikers?

Answers

Answer:

The total number of hikers are 427

Step-by-step explanation:

Let:

The number of bikers = x

The number of hikers = y

There are 178 more bikers than hikers

y = x + 178

if there are 676 people in the park total how many people are hikers?

Hence:

x + y = 676

we substitute x + 178 for y

x + x + 178 = 676

2x + 178 = 676

2x = 676 - 178

2x = 498

x = 498/2

x = 249

y =x + 178

y = 249 + 178

y = 427

Therefore:

The number of bikers = x = 249

The number of hikers = y = 427

The total number of hikers are 427

Step-by-step explanation:

If the triangle is isosceles, then two of the sides must be equal

So we equate the sides, 2 at a time to get the different values of x

3x + 4 = 2x + 10

3x-2x = 10-4

x = 6

3x + 4 = x + 12

3x-x = 12-4

2x = 8

x = 8/2 = 4

2x + 10 = x + 12

2x - x = 12-10

x = 2
