Answer:
s ≥ 60
Step-by-step explanation:
If Scott earned 20 points more on this test, then he earned 20 points less on the last test. 20 points less than "at least 80" is "at least 60."
s ≥ 60
(5*180)/7=900/7=128.5714285714286
The angle is approximately 129 degrees.

You have to use sin, cos, tan and find the length of the last side and other angles. Then you have to put an imaginary line down the middle and use the sin, cos, tan to find the height and then do 1/2 base times height.
