hint for both.
draw a right anglesd triangle.
Label the right angle, and call the other angles theta and beta.
Label the hypotenuse h
call the other 2 sides p and q doesn't matter which is which.
Now what is cos(theta)
and what is sin(beta)
What is theta+alpha ?
What do those word in the answers mean? You can look them up online by yourself if you need to.
Please no one answer over me.
