13) 120 + 1.5 + 0.25 = 121.75 pounds
14) 4 - 1.5 = 2.5 pints
15) (2.25)(32)= $72
i think you just have to do 3 + 14+2+2+3and then solve i guess
I believe it's 36. The vertices have the same x coordinate so I found the difference between the y coordinates.
That is a 180 degree angle (the straight line) and one angle is 78, so you subtract 78 from 180
So the angle would be 102 degrees
