Complementary angles = 90 degrees. Therefore the complimentary angle = 90 -7a

Sin a is not given the complimentary angle could be any value between 0 and 90 degrees. In any event, the correct answer is 90-7a.

If two angles add up to 90 deg, then they are said to be complementary angles, and one is the complement of the other, so the complement of 40 deg is 90-40, = 50deg, and in general, the complement of x degs is{90 – x} degrees.
