Question

Someone help me with this problem? Very confused

Answer 1

Try use Pythagorean Theorem ( \(a^2+b^2=c^2\) )?

Answer 2

@geerky42 oh yeah forgot about that

Answer 3

You have hypotenuse c=12, and leg a=4 or b=4 (let's go with b.)

\(a^2+4^2=12^2\)

Here, we need to solve for a.

\(a^2 = 12^2-4^2\\~\\a=\sqrt{12^2-4^2}\)

Answer 4

Ok so you know what to do?

Answer 5

Answer 6

No problem
