Answer:
x = 18
Step-by-step explanation:
By the rule of Consecutive Interior Angles which define what these angles are, they both will add up to 180. As such we can put the sum of these two angles set equal to 180, and solve algebraically
(8x - 20) + (3x + 2) = 180
8x - 20 + 3x + 2 = 180
11x - 18 = 180
<u> + 18 +18</u>
11x = 198
x = 198/11
x = 18
Answer:
About 39 hours
Step-by-step explanation:
You would do 200/5.15 and get 38.83....
If you round then you get 39.
2/5 = 8/20
8/20 + 5/20 = 13/20
13/20 - 1/4 = 2/5
