The point (-√2/2,√2/2) is the point at which the terminal ray of angle theta intersects the unit circle. what are the cosine and

Helga [31]

since that is the terminal point, then

$\bf \left( \stackrel{\stackrel{x}{cosine}}{-\cfrac{\sqrt{2}}{2}}~~,~~\stackrel{\stackrel{y}{sine}}{\cfrac{\sqrt{2}}{2}} \right)\qquad \qquad cos(\theta )=-\cfrac{\sqrt{2}}{2} \\\\\\ cot(\theta )=\cfrac{\stackrel{cosine}{-\frac{\sqrt{2}}{2}}}{\stackrel{sine}{\frac{\sqrt{2}}{2}}}\implies -\cfrac{\sqrt{2}}{2}\cdot \cfrac{2}{\sqrt{2}}\implies -1$

Solve for the unknown number!

Rina8888 [55]

On the left side use distributive property:
3(n) + (3)(4) = -6 + 15n
3n + 12 = -6 + 15n
Subtract 3n:
12 = -6 + 12n
Add 6:
18 = 12n
Divide 12:
18/12 = n
You can simplify it further:
n = 3/2 or 1.5
