Answer:
270°
Step-by-step explanation:
In a circle graph, the total angle would be 360°. You already know how much of the circle graph is apple juice, so you can find the angle of apple juice out of the entire circle graph.
Angle of apple juice section = × 360°
= 270°
Two angles in the same parallelogram must either be equal or else add up to 180 degrees. These two are obviously not equal, so they must add up to 180.
A + B = 180
A = 180 - B (we'll use this in just a second)
A = 3B + 40
180 - B = 3B + 40
Add 'B' to each side:
180 = 4B + 40
Subtract 40 from each side:
140 = 4B
Divide each side by 4 :
<u>35 = B</u>
A = 180 - B = <u>145</u>
Answer:
B
