Its c first find area of the whole thing with piece cut out.(240) then of the cut out piece (12) 240-12=228 C
Same-side interior angles are supplementary, meaning that they add up to 180 degrees.
5x + 34 + 2x + 76 = 180
7x + 110 = 180
7x = 70
x = 10
Measure of angle A = 5(10) + 34 = 84 degrees
Hope this helps!! :)
Answer:
$17
Step-by-step explanation:
Books = x
1. Set up an equation.
147 - 8x = 11
2. Solve for x
147 - 8x = 11
-8x = 11 - 147
-8x = -136
x = -136 / (-8)
x = 17
So, each book cost $17.
