1)use Pythagoras's Theorem to find the length of the hypotenuse AB of the right angle triangle
5 sqaured = 25
9 sqaured = 81
81+25=106>sqaure root= 10.3cm?
2)use Pythagoras's to find the length of side AC on the right angled triangle
3)use the Cosine rule to find the length 'x' in the triangle
4)find the angle makred '0' in the right angled triangle
5)find angles A and B in the triangle
