Answer:
90°
Step-by-step explanation:
Interior angles of ALL triangles sum to 180°
The whole large triangle has angles 60 60 60 ( they sum to 180)
that means x = 30
then the small triangle on the right has 60 + 30 + y = 180
meaning y = 90 °

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.
