An airplane, flying at an altitude of y = 4.7 miles, is on a flight path that passes directly over an observer (see figure). If θ is the angle of elevation from the observer to the plane, find the distance from the observer to the plane for each value of θ.

theta = 30 degrees

I just want to know if this is the right way to solve this problem:

sin(30 deg) = 4.7/x

x = 1/2

4.7/(1/2
