Answer:
12
Step-by-step explanation:
since tile B is a regular polygon means it is an equilateral triangle. The angle inside B would be 60.
(360 - 60)/2 = 150 (interior angle of tile A)
180 - 150 = 30 (exterior angle of tile A)
therefore number of sides = 360 /30 = 12
I think 51 because if you were to do it reverse then it would be 40x4=160 then -35-36-38 it would be 51.
If I am reading this right, the final total after adding the 55% markup rate should be $159.65.
