Question

Assume that a and b are the legs of a right triangle and C is the hypotenuse.

Given a = 20, c=52, find b =

Answer 1

b = 48

Explanation:

a = 20

b = ?

c = 52

a^2 + b^2 = c^2

20^2 + b^2 = 52^2

400 + b^2 = 2704

b^2 = 2704 - 400

b^2 = 2304

sqrt(b^2) = sqrt(2304)

b = sqrt(2304)

b = 48
