Ok this is not as hard as it seems
(4.5 feet)^2 times the number of students (13)
20.25 x 13
263.25 is the correct answer
Answer:
100° and 80°
Step-by-step explanation:
Ratio means they are sort of multiples of a certain number (which I used X) and A is 5 times X and B is 4 times X. Since they are supplementary they sum 180°. After summing up both angles and equaling them to 180°, solve for X and substitute in the original equations
3x5 = 15, 15^2 = 225.
3^2 = 9 and 5 x + = 45.
225-45 = 180. hope this helps :)
