Answer:
85
Step-by-step explanation:
Use the pythagorean theorem!
(think that is how you spell it )
Pythagorean theorem: a² + b² = c²
a and b are the numbers that you have in this example, c is the side you need!
75² + 40² = c²
5,625 + 1,600 = c²
7,225 = c²
(the square root and square cancel each other out)
85 = c
c = 85
