Question

Find the length of the hypotenuse on a right triangle with legs of 5 inches and 8 inches

Answer 1

sqrt(89)

approx. 9.433981

Explanation:

remember the Pythagorean theorem, where a and b are the legs and c is the hypotenuse

a^2 + b^2 = c^2

now substitute in the given values

a=5

b=8

5^2 + 8^2 = c^2

25 + 64 = c^2

89 = c^2

sqrt (89) = c
