I need help with this.

Looking up, Latoya sees two hot air balloons in the sky as shown. She determines that the lower hot air balloon is 670 meters away, at an angle of 42" from the vertical. The higher hot air balloon is 945 meters away, at an angle of 36" from the vertical. How much higher is the balloon on the right than the balloon on the left? Do not round any intermediate computations. Round your answer to the nearest tenth. Note that the figure below is not drawn to scale. meters 5 2 945 meters 36 42 5 670 meters
