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

14sqaured+3sqaured=sqaure root?

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
