3. The top of the Leaning Tower of Lisa is now only 100 feet from the ground, measuring vertically. To calculate the tower's original height, you walk 200 feet from the base of the tower and measure the angle of inclination (elevation) from the ground to the top of the tower. The angle of inclination (elevation) there is 40°. How tall was the tower originally, to the nearest foot? (a) 131 feet (b) 100 feet (c) 141 feet (d) 129 feet (e) none of these
