Use the calculator.
There is a multiply sign between the 7 and (
Nothing unless you have a value for theta.

For multiplying it does not matter.
mult the numerators for the top.
Multiply the denominators for the bottom
On this calculator they are called
asin, acos, and atan
is that what you mean?

You don't need to worry about the other one.
Well does 17 ^2
Equal
8^2+15^2
If it does then it is a right angled triangle
