See last answer.

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.**
