Answer 2

Answer:

Please mark me as the brainliest

Step-by-step explanation:

Since sin A = cos A , also sin^2 A = cos^2 A

, also sin^2 A + cos^2 A = 1 becomes. 2cos^2 A = 1. ==≥ cos^2 A = 1/2

now ,

2tan^2 A - 2sec^2 A + 5

= 2 [ sin^2 A / cos^2 A ] - 2 ( 1/cos^2 A ) + 5

= 2 (1) - (2/1/2) + 5

= 2 - 1 + 5

= 7 - 1

= 6

So the value is 6
