you need to be able to determine which trig function to use to determine which inverse to apply with its ratio

I do know that the angle of elevation is 39.4

the angle of depression relates to how far he tilts his head to look down, in this case its that same angle at the right side. i think that 39.4 is a bit too big for it tho ... close, but just a little off

it might be worth noting that both cosine and sine use the slanted part of the triangle, and since that measure is not given its prolly best to use the tangent function
