1. Identify the opposite, adjacent, and hypotenuse in relation to angle x.
a)
b)
2. Write the sine, cosine, and tangent ratios for <T and <G.
3. A 20-ft wire supporting a flagpole forms a 35° angle with the flagpole. To the
nearest foot, how high is the flagpole?
What kind of measurement
did we use to find the height
of the flagpole?

tan(25) = 7
x
In context of your triangle, what is x?
(Hint: Draw a picture!)
What if we know the side lengths, but want
to know an angle??
6. Find x.
7. Use the Inverse to find the value of x.
