Question

What is the length of bc in the right triangle below

Answer 1

20

Explanation:

We can use the Pythagorean theorem to solve

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

12^2+16^2 = c^2

144+256 = c^2

400 = c^2

Take the square root of each side

sqrt(400) = sqrt(c^2)

20 = c
