Answer 2

I tried doing the pythagorean theorem, that doesn't get me the answer.

Answer 3

To make it simpler to calculate the value of the hypotenuse, divide 24 and 36 by the HCF giving 2 and 3. Then the value of the hypotenuse is the square root of (2^2 + 3^2 ) \[\large hypotenuse=\sqrt{2^{2}+3^{2}}=\sqrt{13}\]
\[\large \sin\ A=\frac{2}{\sqrt{13}}=\frac{2 \sqrt{13}}{13}\]
Can you find the rest?
