Scientists estimate the height of features on the moon by measuring the length of the shadows they cast on the moon's surface.
From a photograph, you find that the shadow cast on the inside of a crater by its rim is
12 meters long. At the time the
photograph was taken, the sun's angle to the horizontal surface was 30°. How high does
the rim rise above the inside of the
crater?
