She measures the angle of depression of the base of the building to be 32.7 degrees, and the angle of elevation at the top of the building to be 41.9 degrees. Elspeth knows the window is 13.9 m from the ground. How tall is the building across the street?

Use a unit circle. If the marked angles are equal, then the verticle lines have the same length.2. <A is an obtuse angle, and sin A = 0.841. Find <A.
