Question

prove that : (Sin A + tan A ) (1 - sin A) = Cos A​

Answer 1

Answer:

you should write the degree ...

I think your question is like this .

(sin A 90° + tan A 45°) (1-sin A) = cos A 0°

Answer is not equal . LHS not equal RHS

Answer is 1/2..

Step-by-step explanation:

1 + 1 ( 1 -1 ) = 1

2 = 1

2 is not equal to 1.
