Answer:
The least common multiple of 20 and 25 is 100.
Answer:
Step-by-step explanation:
Combine like terms
(x-20) and x are complementary angles which means that they add to 90 degrees. Therefore we can set the sum of the two angles equal to 90 and solve for x.
(x - 20) + x = 90
2x - 20 = 90
2x = 110
x = 55 degrees
You have to know the difference in change, so you do 59-31 and you get 28, then since you want to know the change in percent you divide the difference, which is 28 and divide that by 31, which is the original amount consumed, and you get 28/31, and you get .90 which is 90%
