The height h of the right triangle in the figure below increases at a rate of 10 cm/s, while the base remains constant at x =15 cm. How fast is the angle theta changing when h = 8 ? Round the final answer to three decimal places and give units with your answer. Show all work in the space provided and place your final answer in the answer blank below. I could not add a photo of the right triangle, so please picture a left facing right triangle.
