Need help with maths question.
A 1.5m high fence leans outwards from a house at an angle of 102 degrees. A boy sits on top of the fence and the angle of depression from him down to the house is 32 degrees 44 minutes. How far from the fence is the house?
Please show working out
Thanks
How important is it to maintain/have a good GPA, and what is a good range to have? I'm doing med science if that means anything.

Which would you say is a better approach to be most prepared for HSC physics. To do past paper, or to look at worked solutions/responses to past papers?
Thanks.
