plane ascends at a 40° angle. When it reaches an altitude of one hundred feet, how much ground distance has it covered? To solve, use the trigonometric chart. Round the answer to the nearest tenth.

Answer 1

Assuming a uniform ascending angle of 40° and an altitude of 100', the ground distance is given by
tan(40°) = altitude / ground distance
By the way, tan(40°) = 0.8391

Can you take it from here?

Do you have a trigonometric chart, or are you using the four-figure tables?

Answer 2

Is it, 0.008391
