Answer 6

Yes, but what is the value for it?

Answer 7

Use the Pythagorean theorem.

Answer 8

recall your SOH CAH TOA \(sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}\)

now, you need the sine, well, the sine uses the hypotenuse and opposite
you have the opposite
to find the hypotenuse, as everyone else said, use the pythagorean theorem
