Looks more like Trig than Algebra II
They want us to apply the sum angle formula to 
5π/6 is 150°; I find it easier to think in degrees.
When the tangent of x is 3/4 that's a right triangle with opposite 3, adjacent 4 so hypotenuse 5. So a sine of 3/5 and a cosine of 4/5, both positive because we're told x is in the first quadrant.
The sine sum angle formula is
We know sin 150° = sin 30° = 1/2 and cos 150° = - cos 30° = -√3/2
Third choice
Hello!
First, "the difference" of 2 numbers means you subtract these numbers.
Then, 4 cubed is written as follows:
4³
Subtract:
4³-25
[If necessary] Evaluate:
64-25
39
Hope everything is clear.
Let me know if you have any questions!

Answer:
14 socks.
Step-by-step explanation:
30 socks in total. I think there is a 60% chance you will pull out a black sock??? But that doesn't matter. What if you were really unlucky and you pulled out all the navy socks? Then the answer would be 14 socks. To be CERTAIN, you want to pull out at least 14 socks. 12 socks for the navy. and 2 black socks.
Answer:
y = 2x + 3
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = 2
y-intercept <em>b</em> = 3
<u>Step 2: Write function</u>
y = 2x + 3
