ANSWER

a) £1350

b)£235

c)108°

Step-by-step explanation

The angle that corresponds to Andrew is 72°

The total angle in the circle is 360°

If 72° corresponds to £270,

Then, 360° corresponds to:


= (360 * 270)/(72)

=£1350

Therefore the total weekly income of the 5 employees is £1350.

b) The angle that corresponds to Brian's income is 62°

Brian's weekly income is


= (60)/(360) * 1350

=£225

c) Carol's weekly income is £405

Let x represent the angle representing Carol's weekly income.


(x)/(360) * 1350 = 405


3.75x = 405


x = (405)/(3.75) = 108 \degree
