A radar station located at ground level picks up a plane flying at a direct distance of 47,440 feet away. If the angle of elevation from the station to the plane is 29°, what is the altitude of the plane?

22,999 feets

Step-by-step explanation:

Given the solution diagram attached,

The altitude, h of the plane can be solved using trigonometry :

Using :

Sin θ = opposite / hypotenus

Opposite = h

Hypotenus = 47440

Sin 29 = h / 47440

h = 47440 * sin29

h = 22999.368

h = 22,999 feets

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
