Answer:
The perimeter of the square is
Step-by-step explanation:
Let
x----> the length side of the square
we know that
In an isosceles right triangle the measures of the internal angles are 45°-90°-45°
so
the horizontal distance is equal to the vertical distance
we have
substitute
12-12, it's a decrease so you subtract.
the base of the ramp is 31 inches long.
c = a/sin(α)
= 33.48514
b = √c2 - a2
= √33.4851373155042 - 122
= √977.25442103816
= 31.26107
This is your answer.
Hope is helps!!
