Question

A pilot is beginning his descent to a nearby airport when he is 6.5 miles away. he knows he must have no more than a 3º angle of depression. how high is he above the ground

Pls help

Answer 1

The height of the airport will be given by:
sin θ= opposite/hypotenuse
opposite=x
hypotenuse=6.5 miles
θ=3°
thus
sin 3=x/6.5
solving for x we get:
x=6.5×sin3
x=0.34 miles
Answer: 0.34 miles
