The angle of depression from the hot-air
BlackZzzverrR [31]

Answer:

3497.47 feet

I think it's the answer because when you look where I've drawn...that's where the angle of depression is and 6600 is the hypotenuse, so you use the sine method where you have opposite over hypotenuse

\sin(32 = opposite \6600)

and you'll get your answer as 3497.47

3(x + 7) = 9(x - 1)
3(x) + 3(7) = 9(x) - 9(1)
  3x + 21 = 9x - 9
<u>- 3x          - 3x     </u>
          21 = 3x - 9
        <u>+ 9         + 9</u>
         <u>30</u> = <u>3x</u>
          3      3
