Answer:
? = 32.20422
Step-by-step explanation:
We know the adjacent side and the hypotenuse
cos ? = adj / hyp
cos ? = 33/39

Taking the inverse cos of each side
cos ^ -1( cos ?) = cos^-1(11/13)
? = 32.20422

Hey You!
1.
31.29/6 = 5.215
5.215 × 2 = 10.43
2 brushes cost $10.43
2.
31.29 × 3 = 93.87
93.87 * 10% = 9.387
93.87 - 9.387 = 84.483
3 cases would cost $84.48
