Answer: Choice A

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

========================================================

Work Shown:

\cos(30) = \frac{\sqrt{3}}{2}

\cos(\frac{x}{2}) = \sqrt{\frac{1+\cos(x)}{2}

\cos(\frac{30}{2}) = \sqrt{\frac{1+\cos(30)}{2}

\cos(15) = \sqrt{\frac{1+\frac{\sqrt{3}}{2}}{2}

\cos(15) = \sqrt{\frac{\frac{2}{2}+\frac{\sqrt{3}}{2}}{2}

\cos(15) = \sqrt{\frac{\frac{2+\sqrt{3}}{2}}{2}

\cos(15) = \sqrt{\frac{2+\sqrt{3}}{4}}

\cos(15) = \frac{\sqrt{2+\sqrt{3}}}{\sqrt{4}}

\cos(15) = \frac{\sqrt{2+\sqrt{3}}}{2}

\cos(15) = \frac{0.5\sqrt{6}+0.5\sqrt{2}}{2}  

\cos(15) = \frac{\sqrt{6}+\sqrt{2}}{4}

Graph the equation<br> y = 5x<br> Use the graphing tool to graph the line.
taurus [48]

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

You want a line that goes through (0, 0) and has a slope of 5. That means it will also go through (1, 5) and (2, 10), for example. I like the attached graphing tool because it will draw the graph directly from the equation.

Use the figure to find the measures of the numbered angles. Explin your reasoning.
Reika [66]
1)81° due to the fact that 99° and (1) are supplementary angles
2)99° due to the fact that (5) and (2) are adjacent angles that sum up to equal 180°  
3)81° due to the fact that it is the corresponding angle to (5)
4)99° due to the fact that (4) and (2) are alternate interior angles which equal the same 
5)81° due to the fact that (5) and (6) are adjacent angles which means they are supplementary angles that add to equal 180°
6)99° due to the fact that (6) and (2) are corresponding angles which equal the same value
7)81° due to the fact that (7) and (3) are corresponding angles with equal the same degree
