Hi everyone,

I’m a math tutor and quite embarrassingly, I’m hahing a tough time solving this problem. There may well be a really simple solution to it but I’m just not seeing it for some reason. Any help would be greatly appreciated.An aircraft flying at a height of 500m above ground is sighted at a point A’ due east of an observer at a point O on the ground, measured horizontally to be 1km from the plane. The aircraft is flying south-west.

a) find its bearing from O at this time? (answer is 215.65)

b) what will be it’s angle of elevation from O at this time? (Answer is 6.55)

This has me utterly baffled I’m afraid, sigh 😔

Please help! Thank you 😊
