You first find the average of the first two test scores. When you find the average, you add the two numbers together and then divide by two which gives you 89. You then plug in different scores above the number 89 and find the average of those (89 and x) to see which gives you an average of 92. It’s mostly a guess and check type of problem.
UT = 3 √3
A = 1/2 *12 * 3√3 = 18√3
18√3 = 6y/2
y = 6√3
