Answer:
how to do what? there is no question attached
Step-by-step explanation:
Parallel lines have equal slopes, so if green line has slope = -2 then, red line's slope would be equal to -2
In short, Your Answer would be Option A
Hope this helps!
Cross multiply the expression so that we can get
(1+sinx)(1-sinx) = cos^2 x
1 - sin^2 x = cos^2 x
cos^2 x + sin^2 x = 1
since
cos^2 x + sin^2 x = 1
therefore
1 = 1
the two expressions are identical in a trigonometric sense
