Question 972992: An airplane flying at an altitude of a is on a flight path that passes directly over an observer (see figure). What is the altitude of the plane if is the angle of elevation from the observer to the plane is 30°, and the straight line distance d from the observer to the plane is 1.3 miles.

You can put this solution on YOUR website! Angle at the observer, 30 degrees. HYPOTENUSE, 1.3 miles. Simple enough trigonometry information for a right triangle.
