Answer:
It will cost $190.75 to paint the whole fence.
Step-by-step explanation:
109 * 7 = 763 because Length x Width = Area
0.25 * 763 = 190.75
The reason you got it wrong is because you solved for the side a instead of the angle Z, which was what the question asked you to solve for. You can find Z by doing cos Z = 12/35, which will get you cos Z = 0.343, and Z will be equal to about 70º.
That is $32.00 hope this is right
