Match each ratio in the first row with an equivalent ratio from the second row if angle A plus angle B = 90 degrees.

SinA CosA TanA CscA SecA CotA
SinB CosB TanB CscB SecB CotB

Does this question even make sense?

Yes, the question makes sense. In trigonometry, when the sum of two angles is equal to 90 degrees, they are considered complementary angles. Since the question states that angle A plus angle B equals 90 degrees, it can be inferred that angles A and B are complementary angles. You are asked to match each ratio in the first row with an equivalent ratio from the second row under this condition.

Yes, the question does make sense. It is asking you to match each trigonometric ratio in the first row (SinA, CosA, TanA, CscA, SecA, and CotA) with an equivalent trigonometric ratio from the second row (SinB, CosB, TanB, CscB, SecB, and CotB). The condition given is that angle A plus angle B equals 90 degrees, which means that the two angles are complementary. Therefore, you will need to find the corresponding trigonometric ratios for angles that add up to 90 degrees.
