Question

1. Given a triangle with leg A = 12 and the hypotenuse C = 20, find the the length of leg B.

Answer 1

please, is your triangle a right triangle?

Answer 2

that is the full question

Answer 3

Since I see the term "hypotenuse", I think that it is a right triangle

Answer 4

So in order to find B, you can apply the Pitagora theorem, namely:
\[B ^{2}=C ^{2}-A ^{2}\]

Answer 5

can you please solve it so i can see how you do it

Answer 6

ok!

Answer 7

\[B ^{2}=20^{2}-12^{2}=400-144=256\]
so, we have:
\[B=16\] since 16^2=256
