Year 10 question on Bearings

Hello all,

Just been looking over my test paper going over the questions I need work on. I don't usually have a problem with bearings, but I seem to be getting nowhere with this one.

Appreciate any help - I know I must be overlooking something obvious!!


Thanks!

Have you made any progress? Post all your working / thoughts.

If you haven't done anything then the first to do is to realise that the triangle is isosceles so you can find the other two angles in the triangle.

That's great - seemed to have overlooked that! Angle BAC = BCA = 65º.

So solution = 65 + 70 = 135 º

Thanks for your help!!!

Kind Regards,
