From his position in a hot-air balloon, Steve can see a kangaroo in a field. If the angle of depression is 8° and Steve is 38 meters above the ground, what is the straight-line distance from Steve to the kangaroo?

The answer would be 5< 6n

I'm a bit puzzled here because they did not provide you with any measures of the other angles, so i am unable to provide a theorem or postulate to support my answer, but i'd say 90 degrees because it looks closer to a right angle than anything.
