Looking up Carlos sees two hot air balloons in the sky as shown. He determines that the lower hot air balloon is 515 meters away, at an angle of 15° from the vertical. The higher hot air balloon is 840 meters away at an angle of 22° from the vertical. How much higher is the balloon on the right from the balloon on the left? Do not round any intermediate computations. Round your final answer to the nearest tenth. (one decimal) Note that the figures are not drawn to scale.
