(sin A + cos A). sec A = sin A. sec A + cos A. sec A =(sin A/cos A)+1 (Since sec A = 1/cos A )
= tan A +1 (Since tan A = sin A/cos A )
= 17/12
= tan A +1 (Since tan A = sin A/cos A )
= 17/12

(5/13 +12/13)×13/12
17/13×13/12=221/156
=17/12
17/13×13/12=221/156
=17/12
You have do in short but I have done long method
