20
Step-by-step explanation:
This reads mathematically exactly how it is stated in words. The word "is" means =, the word "of" means multiply, and "what number" is x. Therefore, the equation from that looks like this: 16 = .80x. Don't forget that you cannot use a percent in an equation without first changing it to its decimal equivalency. Solve that for x by dividing both sides by .80 to get that x = 20
“y” is a part of a straight angle, so
131 + y = 180
y = 180 - 131
y = 49 [degrees].
