How do you find the side lengths of a right triangle if you have all the angles?

To find the length of the leg, substitute the known values into the Pythagorean Theorem. A^2 + B^2=C^2

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
