Question

If u answer this question ill mark u as brainist​

Answer 1

Step-by-step explanation:

sin43 sec47-cos51 cosec39 = tanA

sin43/cos47 - cos51/sin39 = tanA

sin43/sin43 - cos51/cos51 = tan A

1-1 = tanA

tanA= 0

If you are in 10th or below your answer will be A=0

If you are in 11th you need to answer A=

$n\pi$

Hope it helps you.
