In triangle $ABC$, angle $A = 50^\circ$, angle $B = 72^\circ$ and side $a = 13$ cm. Work out the length of side $b$, to 1 decimal place. [3]

2

In triangle $ABC$, $b = 11$ cm, $c = 10$ cm and the angle $A = 119^\circ$ between them. Work out the length of side $a$, to 1 decimal place. [3]

3

A triangle has two sides of length 6 cm and 14 cm with an angle of 136$^\circ$ between them. Work out the area of the triangle, to 1 decimal place. [3]

4

In triangle $ABC$, angle $A = 55^\circ$, angle $B = 62^\circ$ and side $a = 8$ cm. Work out the length of side $b$, to 1 decimal place. [3]

5

In triangle $ABC$, angle $A = 67^\circ$, side $a = 9$ cm and side $b = 6$ cm. Side $b$ is shorter than side $a$, so angle $B$ is acute. Work out the size of angle $B$, to 1 decimal place. [3]

6
