if angle a and angle b are complementary angles ,angle = (2x+11) degrees and angle b = (10x - 17)degrees , what is angle a

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

Answer is either b or c
