Explain the answer with briefs steps​

And explain how you got it so i can understand future problems : 3

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180
