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
angle formed by the hypotenuse and the _________________ side.

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
