a circular pizza pan whose diameter is 20 inches costs $13.32. Assuming the cost depends upon the size(area) of the pan, what would be the cost of a similar pan whose diameter is 8 inches?

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
