Use the figure at the right to name the following. 8. a pair of supplementary angles

Balloon B is 3910 feet above balloon A.

Step-by-step explanation:

The figure for the given scenario is shown below.

From the figure,

QR is the distance of balloon A or B from Charlie, SR is the distance of balloon A from ground, is the angle of elevation of balloon A, is the angle of elevation of balloon B. S is the position of balloon A and P is the position of balloon B.

So, as per the question,

SR = 1200 ft, °, °.

From triangle ΔSQR,

Now, consider triangle ΔPQR.

Now, difference in the height of balloon A and B is given by the segment PS.

So,

Therefore, the balloon B is 3910 feet above balloon A.
