While in his garden, Simon sees that the sunflower sculpture he made is casting a long shadow. He sees this as an opportunity to use some of the trig his teacher raved about a few months ago. He knows the top of the sculpture is 8.5 feet above ground, and he measures the length of the shadow (on the ground) to be 15 feet. Help Simon find the angles of depression and elevation related to the sunflower’s shadow at this point.
