if in a parallelogram ABCD, m angle b=8x25 an m angle c=7x+55 how do i solve this probblem

How many degrees are in all the angles of a parallelogram? 360, right? There will be 2 angles the same measure as b and 2 angles the same measure as c. Therefore, 2(8x25)+2(7x+55)=360. Solve for x and plug it into your original equation and you will have the answer.
