The circuit represents 360°
So, let the angle represent 1/18 = β
∴ β = (1/18) * 360° = 20°
∴ The correct choice is 20°
Start at -2 on the y axis then go to the left 5
(2,-5) (3,-3)
You could estimate the $337 to $335.
You could estimate the $103 to $105.
335 - 105 = 230.
$230 is therefore the estimated answer.
The exact answer is as follows:
337 - 103 = 234.
$234 is therefore the exact answer.
Hope I helped.
