Question 830180
A diagonal through a rectangle is the hypotenuse of a right angle triangle.
We know that a^2 + b^2 = c^2 for a right triangle where a and b are the vertical and horizontal measurements.(the ^2 means "squared")
You're given a as 120m.
You're given b as 90m
Find c.
120^2 + 90^2 = c^2
14400 + 8100 = c^2
22500 = c^2
Square root of each side:
150 = c (the diagonal)
