If m∠13=2x-3 and m∠15=71°, find the value of x.<br> Show work please
sineoko [7]
<h3>The value of x is 37</h3>

Here ∠13 & ∠15 are corresponding angles , so they are equal [ ∠13 = ∠15 ]

As per the question ,

⇒ 2x - 3 = 71°

⇒ 2x = 71 + 3

⇒ 2x = 74

⇒ x = 74 ÷ 2

⇒ x = 37

Hence , x = 37

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
