Question

in a right triangle the length of a hypotenuse is c and the length of one leg is a and and the other leg is b, what is the value of b if: c=2b, a=12

Answer 1

Use the Pythagorean Theorem:

\(\large a^2+b^2=c^2\)

You have: a=12, and c=2b

So:
\(\large 12^2+b^2=(2b)^2\)

Solve that for b.

The answer is NOT b=12.
