The statement that correctly calculates the average price of Will's books is
B. ($32 + $45 + $39) ÷ 3
This is because the average or mean, is found by adding all of the numbers together and then dividing the sum by the amount of numbers you added together (in this case 3.)
Since quadrilaterals have interior angles that add up to 360, then subtract the known values from 360
360 - 90 - 90 - 146 = 64
Angle C = 64
I think most of them are correct, you might wanna doubke check though! :)
