Answer 1

Answer:

antha good question........

Step-by-step explanation:

L,H.S, = Sin(90-A) /1- Tan A + Cos(90-A) / 1- Cot A

= Cos A (1-Cot A) / 1- Tan A + Sin A

= Cos A [ 1- Cos A/Sin A ] / 1- ( Sin A/Cos A) +Sin A

= Cos A [ Sin A - Cos A / Sin A] / Cos A - Sin A + sin A Cos A / Cos A

= Sin A + Cos A

=R.H.S.
