Hey!
You can round 83 and 57 to the closest whole numbers:
80 × 60 = 4,800
So, now you know that your answer should be close to 4,800
Answer:
60
Step-by-step explanation:
Angle AFC is supplementary to angle CFE. Supplementary angles always equal 180 degrees. (180-120=60)
That's the wrong right triangle to draw. Reading the problem carefully we want this one, figure attached.
So we have the usual 30/60/90 triangle but not to scale. The sides come in ratio 1:√3:2=x:100:hypotenuse. So
x = 100/√3 ≈ 57.735
We add that to our 133.2 for the total height of the Cyclone, 190.935.
Answer: 190.9
