Question 47633
The approach pattern to an airport requires pilots to set an 11 degree angle of decent toward a runway.If a plane is flying at an altitude of 9,500 m at what distance (measured along the ground) from the airport must the pilot descend?-Thank you!

Draw the picture.
You get a right triangle with side of 9500 across from the 11 degree angle.
Let "x" be the length of the side adjacent to the 11 degree angle.
EQUATION:
tan(11 degrees) = 9500/x
x=9500/tan(11 degrees) = 48873.26 m
Cheers,
