Answer:
x = 52.5
Step-by-step explanation:
The triangle on the left has 2 congruent sides, thus is isosceles
The base angles of an isosceles triangle are also congruent, thus
x = 
= 
= 52.5
In order to answer this, we need to know the formula of finding a perimeter.
By definition, perimeter is the sum of all the sides of a polygon.
The given is a square with a side length of 2 3/5 feet.
The perimeter of a square is 4*S
Perimeter = 4 * S
Perimeter = 4 * (2 3/5)
Perimeter = 4 * (13/5)
Perimeter = 52/5 feet
So the perimeter is 52/5 feet of 10 2/5 feet.
