Answer:
a=21.1
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 full revolutions, so is back where it started — at 12.5 feet above the ground.

X = 128
180-52=128
The straight line that goes between the 90 degree angle forms a linear pair with one angle being 52 degrees. Since a straight line is a 180 degree angle, you can subtract 52 from 180 to get the 2nd angle which is 128.
