Your θ is in the 2nd quadrant, so -θ is in the third quadrant. The secant function is the reciprocal of the cosine function, so is negative in the third quadrant.

The sign of sec(-θ) is negative.

Answer:

Step-by-step explanation:

i assume x+y=6(1/2)=\frac{13}{2}

$\frac{5}{8}=\frac{x}{y}=\frac{x}{\frac{13}{2}-x}=\frac{2x}{13-2x}\\65-10x=16x \\26 x=65\\2x=5\\x=\frac{5}{2}\\y=\frac{13}{2}-\frac{5}{2}=\frac{8}{2}=4$
