Question 35 - Mathematics Practice Test for the ACT

You are at a garage sale and find a clock that you like. When you get home, you realize that the clock is stuck with the hands in the positions shown in the visual. Before replacing the hands, you decide to calculate the degree measurements of the angles generated when a straight line is drawn from the short hand to the long hand. The long arm measures 12 cm, and the short arm measures 9 cm. What is the measure of the angle formed between the long arm and the hypotenuse?
