An airplane pilot over the pacific sights an atoll at an angle of depression of 10 degrees. at this time, the horizontal distance from the airplane to the atoll is 3,172 meters.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
