Did you label the angles like the ones below? If not, go back and read the frame again to

find why you are wrong.

The angle we will use in this program to solve problems is angle theta. Theta is the

We will use three trigonometric functions in this program. One of these functions is the

SINE function (abbreviated sin). The drawing below shows the sides used in solving for

the sine function.

When solving for the sine of

the vertical side of a right triangle is the side
