Answer:
Draw the triangle. The 75 degree angle is between the base and the hypotenuse. The h is the side opposite that angle, while the 10,000 base is the side adjacent to that 75 degree angle.
This is a job for tan = opp/adj = h/10000.
tan75 = 3.7321 = h/10000 (multiply both sides by 10000) h = 37321 feet.
