The only point which is a solution is C
A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11
Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°
Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°
Answer:

Answer: The answer is 1/2
Step-by-step explanation:
Find the volume of each size stack by multiplying Length x width x height.
Once you have the volume for the 3 different stacks of books, add the together.
Bottom: 12 x 1 x 6 = 72 cubic inches per book x 2 = 144 cubic inches total.
Middle: 10 x 1 x 5 = 50 cubic inches per book x 2 = 100 cubic inches total.
Top: 7 x 0.5 x 4 = 14 cubic inches per book x 2 = 28 cubic inches total.
Total volume = 144 + 100 + 28 = 272 cubic inches.
