i need help with this problem.an airplane over the pacific sights an atoll at an 8 angle of depression. if the plane is 520 m above water, how many kilometers is it from a point 520 m directly above the center of the atoll?

Answer 1

Did you make a sketch??
I have a right-angled triangle with a angle of 8°, the adjacent side as x , and the opposite as 520 m
520/x = tan 8°
x = 520/tan 8 = 3699.99
I guess we can say 3700 m or 37 km

(I also think we have to ignore the curvature of the earth)
