Question

Determine whether each expression can be used to find 2. Select Yes or No.

x=12 cos 36
x=12/cos 36
x=12 sin 54
x= 12/sin54

Answer 1

If you have the hypotenuse, multiply it by sin(θ) to get the length of the side opposite to the angle. Alternatively, multiply the hypotenuse by cos(θ) to get the side adjacent to the angle. If you have the non-hypotenuse side adjacent to the angle, divide it by cos(θ) to get the length of the hypotenuse.
