The values of C , a and b are 40° , 32.97 and 13.99 respectively.

1.)

From the diagram;

∠C = 180 - (118 + 22)

∠C = 40°

2.)

The sine rule is:

  • sinA/a = sinB/b = sinC/c

sinA/a = sinC/c

sin(118) / a = sin(40) / 24

3.)

sinB/b = sinC/c

sin(22)/b = sin(40)/24

4.)

We can calculate the value of 'a' thus ;

sin(118)/a = sin(40)/24

a * sin40 = sin(118) * 24

a = 32.97

5.)

sin(22)/b = sin(40)/24

b * sin(40) = sin(22) * 24

b = 13.99
