(I already did the first part) Describe two different ways you could find the measure of angle CFD. What is the measure of this angle? hope I can get this soon, thanks :)

Which ratio is equivalent to 10: 85

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.

Which number produces a rationale number when multiplied by 1/5
