Answer: Opposite angles

Step-by-step explanation: As you can see, angles B and D are opposite from each other and they have matching angles. Angles A and C are opposite from each other and they have matching angles. So the opposite angles are congruent. Congruent = identical

If sin theta = 2/3 and tan theta <0 what is the value of cos theta?

Mrac [35]

Answer:

d) $\cos(\theta)=-\frac{\sqrt{5}}{3}$

Step-by-step explanation:

If $\sin(\theta)=\frac{2}{3}$ and $\tan(\theta)\:$ , then

$\theta$ is in quadrant 2.

Recall that;

$\sin^2(\theta)+\cos^2(\theta)=1$

We substitute the given sine ratio to obtain;

$(\frac{2}{3})^2+\cos^2(\theta)=1$

$\frac{4}{9}+\cos^2(\theta)=1$

$\cos^2(\theta)=1-\frac{4}{9}$

$\cos^2(\theta)=\frac{5}{9}$

$\cos(\theta)=\pm \sqrt{\frac{5}{9}}$

$\cos(\theta)=\pm \frac{\sqrt{5}}{3}$

We are in the second quadrant, therefore

$\cos(\theta)=-\frac{\sqrt{5}}{3}$
