An observer 2.5 miles from the launch pad of a space shuttle launch measures the angle of elevation to the base of the shuttle 25 degrees soon after lift-off. How high is the shuttle at that instant?

(Assume the shuttle is still moving vertically.)
Try apply some basic trigonometry . Perhaps draw a triangle diagram to make it easier .
The observer is 2.5 miles away and the angle of elevation from the launch pad to the shuttle's base is 25 degree.
