$\sin \theta = \dfrac 2 3$

$\tan \theta < 0$

Positive sine, negative tangent, means we have a negative cosine. We're talking about the second quadrant.

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

$\cos^2 \theta = 1 - \sin ^2\theta$

$\cos \theta = \pm \sqrt{1 - \sin ^2\theta}$

We know it's negative,

$\cos \theta = - \sqrt{1 - (2/3)^2} =-\sqrt{5/9} = - \dfrac 1 3 \sqrt{5}$

Answer: -(1/3)√5

A + C

Step-by-step explanation:

n = how much the guitar costs.

You know that you spent $45 on the lesson, and the cost of the lesson plus the cost of the guitar equals 325.

280 comes from 325, the cost of the guitar and the lesson, plus the cost of the lesson.

hope this helped! :)
