Answer:
Hence, The reciprocal of tan B is tan A
B is correct.
Explanation:
We are given a right angle triangle. Right angle at ∠C
We need to find the reciprocal of tan B
First we write the formula of tan B using trigonometry identity.

In ΔABC, ∠C=90°

Now we reciprocal it.


Comparing both equation ( Right sides equal )


Hence, The reciprocal of tan B is tan A.
