Answer:

x = 39

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x + x + 12 + 90 = 180

2x + 102 = 180 ( subtract 102 from both sides )

2x = 78 ( divide both sides by 2 )

x = 39

Then

x = 39°

x + 12 = 39 + 12 = 51°

Choose all of the points that would be on a graph for y=7x

pav-90 [236]

Hey there! :D

Plug in the points to see if they work.

y=7x

(2,14) -> (x,y)

14=7*2

14=14

That works.

(0,0)

0=7*0

0=0

That works

(1,7)

7=7*1

7=7

That works.

The points that work are (2,14), (0,0), and (1,7)

I hope this helps!

We want to place a bench measuring 7.05 feet in the center of a platform that is 40.75 feet long

AnnyKZ [126]

40.75 - 7.05= 33.7
33.7 / 2 = 16.85
16.85 ft. should be on each side of the 7.05 ft. bench

A school gymnasium is being remodeled. The basketball court will be similar to an NCAA basketball court, which has a length of 9

valkas [14]

Answer:

Perimeter of NCAA court=288 feet

Perimeter of new court=259.2 feet

Step-by-step explanation:

We are given that

Length of NCAA court, l=94 feet

Width of NCAA court, b=50 feet

Width of new court, b'=45 feet

We have to find the perimeter of an NCAA court and new court in the school.

Perimeter of NCAA court= $2(l+b)$

Perimeter of NCAA court= $2(94+50)$ feet

Perimeter of NCAA court=288 feet

When two rectangles are similar then the ration of their corresponding sides are equal.

Using the property

$\frac{Perimeter\;of\;NCAA\;court}{Perimeter\;of\;new\;court}=\frac{Width\;of\;NCAA\;court}{Width\;of\;new\;court}$

$\frac{288}{Perimeter\;of\;new\;court}=\frac{50}{45}$

Perimeter of new court= $\frac{288\times 45}{50}$ feet

Perimeter of new court=259.2 feet
