You are trying to pick 2 elective classes for next year. you are required to take 1 elective from the fine arts department and 1 from the foreign languages department. there are different fine arts classes and 8 different foreign languages classes offered at your school. how many different combinations of these elective classes can you select?

If there are four choices for fine-arts, which there probably is (choir, band, orchestra, and, drama) and eight language choices you will have 32 combinations possible when taking one of each (language and fine arts) as that is the requirement. 

8 language choices by 4 fine arts choices gives you 32 total options 

P.S. Sorry if i'm wrong, but hope it helps! 

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
