Answer:

The measure of reference angle is $30^{\circ}$ .
$\cos \theta=\frac{\sqrt{3}}{2}$

Step-by-step explanation:

Converting $\theta$ to degrees,

$\theta=\left(\frac{11\pi}{6} \right) \left(\frac{180}{\pi} \right)=330^{\circ}$

This means $\theta$ lies in Quadrant 4, and thus its reference angle is $360^{\circ}-330^{\circ}=\boxed{30^{\circ}}$

Since $\theta$ lies in the fourth quadrant, $\sin \theta$ and $\tan \theta$ are negative.

Since $\theta$ lies in the fourth quadrant, $\cos \theta$ is positive, and is equal to $\cos (30^{\circ})=\boxed{\frac{\sqrt{3}}{2}}$

Step-by-step explanation:

Convert the equation to the slope-intercept form (y = mx + b):

$-5x-3y=-7$ <em>add 5x to both sides</em>

$-3y=5x-7$ <em>divide both sides by (-3)</em>

$y=-\dfrac{5}{3}x+\dfrac{7}{3}$

Choose any three values of x and calculate the values od y:

for x = -1:

$y=-\dfrac{5}{3}(-1)+\dfrac{7}{3}=\dfrac{5}{3}+\dfrac{7}{3}=\dfrac{12}{3}=4\to(-1,\ 4)$

for x = 2:

$y=-\dfrac{5}{3}(2)+\dfrac{7}{3}=-\dfrac{10}{3}+\dfrac{7}{3}=-\dfrac{3}{3}=-1\to(2,\ -1)$

for x = 5

$y=-\dfrac{5}{3}(5)+\dfrac{7}{3}=-\dfrac{25}{3}+\dfrac{7}{3}=-\dfrac{18}{3}=-6\to(5,\ -6)$
