Question

(secA + tanA)(1-sin A) -
(a) sec A
(b) cosec A
(c) sin A
(d) cos A​

Answer 1

Answer:

(d)cos A

Step-by-step explanation:

sec A=1/(cos A)

tan A=(sin A)/(cos A)

sec A+tan A=(1+sin A)/(cos A)

(sec A+tan A)(1-sin A)=((1+sin A)(1-sin A))/(cos A)

=(1 - sin^2 A)/(cos A)

=cos^2 A/cos A

=cos A

Answer 2

Answer:

option D is correct
