This is classic right triangle trig. First decide how each side is related to the angle theta. The side 7.7 is opposite the angle theta, while the side 14 is adjacent. That is the tangent ratio by definition. Setting up the tan ratio:

$tan\theta=\frac{7.7}{14}$

To find a missing angle on your calculator, hit the 2nd button, then the tan button and enter in 7.7/14 and hit enter. You should get an angle measure of 28.8°

If you did not get 28.8 then you are probably in radians. Check it in the "mode" of your calculator.

What are supplemenatry angles

telo118 [61]

Answer:

Supplementary angles are two angles that add up to 180 degrees.

Step-by-step explanation:

They angles don't have to be next to each other to be supplementary, just so long as the total is 180 degrees. Examples: • 60° and 120° are supplementary angles.
