Answer:
sinA=0.8 <-- I don't know what format you need your answer in
Explanation:
Think of SOH CAH TOA.
Because you're solving for sin you want to use SOH. Meaning sin = opposite over hypotenuse.
The opposite in this situation is 32 because it is opposite from angle A.
The hypotenuse is 40 because it is always the side opposite the right angle.
When you plug those numbers into your equation you get sinA=32/40 which equals 0.8
