Question

If you know the length of sides b and c of a right triangle, which equation represents the length of side a, according to the Pythagorean theorem?

Answer 1

A=SqRt(c^2-b^2)

Explanation:

a^2 + b^2 = c^2

rearrange to solve for a^2

a^2= c^2-b^2

take the square root of each side

a= square root (c^2-b^2)
