Two planes take off at a ny airport.
The first plane climbs at an angle of 45 degrees with respect to the ground and reaches an altitude of 5600 feet.
The second plane climbs at an angle of 60 degrees with respect to the ground and reaches an altitude of 8200 feet.
To the nearest foot, which plane covers a longer ground distance?
:
We can use the tangents of the angles, where side opposites is the alt
and side adjacent (sa) is the ground distance.
:
Tan(45) = 5600%2F%28sa%29
sa = 5600%2Ftan%2845%29
sa = 5600
:
Tan(60) = 8200%2F%28sa%29
sa = 8200%2Ftan%2860%29
sa = 4734

Which is greater? makes sense.
The "to the nearest foot" makes no sense.
