An aircraft takes off and climbs at a constant 29 degree angle until it reaches and altitude of 6 miles. At that point, how far away is the plane from the airport?

Answer 1

Did you make a sketch?
What you have is a right-angled triangle with a base angle of 29°, a height of 6 and the hypotenuse is what we want, call it h
6/h = sin 29°
h = 6/sin29°
= 12.38 miles
