Find the exact value of sin 105 degrees​
STALIN [3.7K]

Answer:

\frac{\sqrt{6}+\sqrt{2}}{4}

Step-by-step explanation:

I'm going to write 105 as a sum of numbers on the unit circle.

If I do that, I must use the sum identity for sine.

\sin(105)=\sin(60+45)

\sin(60)\cos(45)+\sin(45)\cos(60)

Plug in the values for sin(60),cos(45), sin(45),cos(60)

\frac{\sqrt{3}}{2}\frac{\sqrt{2}}{2}+\frac{\sqrt{2}}{2}\frac{1}{2}

\frac{\sqrt{3}\sqrt{2}+\sqrt{2}}{4}

\frac{\sqrt{6}+\sqrt{2}}{4}

Which graph best represents the solution set of 2/3x + y ≤ − 2?
DochEvi [55]

Answer:

Step-by-step explanation:

The answer is D. Easy way to tell, the less than or equal to sign indicates a solid line in the graph. Equal=solid line. Also when you solve for y, the slope of the line (-2/3)is negative, indicating a line sloping downward.
