Two surveyors, Warren and MJ, need to determine the height of a steep cliff. They stand 50 m apart where they each have clear view of the cliff and each other. MJ measures an angle of elevation of 61◦ from the base of the cliff to its highest point. He also measures the angle between Warren and the base of the cliff as 72◦. Warren measures the angle between MJ and the base of the cliff as 38◦. How tall is the cliff in meters?
