Question

Can anyone explain me (a)

Answer 1

ANSWER

a) £1350

b)£235

c)108°

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:

$= \frac{360 \times 270}{72}$

=£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

$= \frac{60}{360} \times 1350$

=£225

c) Carol's weekly income is £405

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

$\frac{x}{360} \times 1350 = 405$

$3.75x = 405$

$x = \frac{405}{3.75} = 108 \degree$
