Question

Let A = 40. If B is complement of A, and C is a supplmenet of B, what is B+C?

Answer 1

Option C: 180 
Explanation:
 Complementary angles add upto 90 degrees and supplementary angles add to 180 degrees
 Given A=40
 B = Complement of A =90-40 =50
 C = Supplement of B = 180-50 =130
 Therefore B+C = 50 +130 =180.
