Since there are 2 semesters per year we have:
(1/2)(24,870 - 7,560) = $8,655
David would have to contribute $8,655 per semester.
All three sides always add up to 360 so add the given measures and subtract it from 360 and that would give you your answer.
That is a fraction but if you want it simplified
i believe 999/1000
The answer to the first question is b
I don’t know the answer to the second one sorry
