Answer:
65.4
Step-by-step explanation:
Use the Law of Sines here. The Law is as follows:
We only have need for 2 of those 3 proportions. Since we can have only 1 unknown in a single equation, we have to use angle C as that unknown. That means that other angle and side have to be given in the problem. Angle B is given as 45 and side b is given as 7, so we will use those.
We solve for sinC:
Doing that on our calculator gives us
sinC = .9091372901
Taking the inverse sin in degree mode gives you that angle C = 65.4
