PLEASE HELP ME

A homeowner wants several small dormers built on his roof to admit light. They will be in the shape of isosceles triangles whose sides will exceed their base by 5 inches. If the perimeter is 100 inches, what are the lengths of the three sides?

The base is? , and the equal sides are ?.

An isosceles triangle has common sides a and a base b.

The perimeter is 100, so

a+a+b = 100

2a + b = 100

The sides exceed the base by 5,

a = b+5

2(b+5)+b = 100

3b + 10 = 100

3b = 90

b = 30

a = b+5 = 35

The base is 30 and the equal sides are 35.

base = 30, sides = 35

Step-by-step explanation:

The easiest way to solve your question is by creating an equation.

We can represent the perimeter as "p" and each side as "s"

s + (s + 5) + (s + 5) = p

10 + 3s = 100 (p = 100)

3s = 90

s = 30.Thus, the base = 30, and the sides are 35.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
