Steve and Abby are at the beach... Answer the questions below!

If Steve and Abby are standing 9 metres apart and Abby throws the ball 11 metres above Steve's head, at an angle of elevation of 51 degrees, how far did Abby throw the ball? (To the nearest m)

For the above question, do you need the angle of elevation to find the answer?

If the angle of elevation is 51 degrees (given), what is angle of depression of the ball to Abby? Assume angle C is a right angle.

What is the angle of CAB?

If Steve and Abby were standing closer together, would the angle of elevation be smaller or larger? Explain.
