Given that tan 0=-4/7 , and 270 degrees <0<360 degrees , what is the exact value of sec0?
Accepted Solution
A:
I take it you meant θ angle, anyway.
we know the tan(θ) = -4/7... alrite, we also know that 270° < θ < 360°, which is another to say that θ is in the IV quadrant, where the adjacent side or "x" value is positive whilst the opposite side or "y" value is negative.
