8am : -14F

noon : -14+10 = -4F

increase between noon and 4 is 2*10 =20

4 pm: -4F + 20 = 16F

How do you find the exact value of sec θ if sin θ = -15/17 and 180 < θ < 270?

AnnyKZ [126]

For $180^\circ$ , we expect to have $\cos\theta$ . Then if $\sin\theta=-\dfrac{15}{17}$ , we have

$cos^2\theta+\sin^2\theta=1\implies\cos\theta=-\sqrt{1-\sin^2\theta}=-\dfrac8{17}$

$\implies\sec\theta=\boxed{-\dfrac{17}8}$
