What are the steps to this?
Volgvan

Answer:

Start at the positive

x

-axis, then rotate left by the desired angle.

Explanation:

Standard position means the first arm of the angle is the positive

x

-axis, and the other arm is placed by rotating counter-clockwise from there, by the amount of the angle.

As a basic example, the symbol

∠

is about a 45° angle in standard position.

To get a feel for where the second arm (called the "terminal arm") will go, remind yourself that the axes themselves meet each other at 90°.

If our angle was 90°, the terminal arm would be on the positive

y

-axis.

If our angle was 180°, it would be on the negative

x

-axis.

Wait! 180° is more than 150°, so our angle is somewhere in quadrant 2. In fact, 150° is 2/3 of the way between 90° and 180°, so our terminal arm will be 2/3 of the way into quadrant 2.

graph{(y+tan(pi/6)x)(y^2-.00001x)=0 [-10, 10, -5, 5]}

(ignore the part of the line in quadrant 4)

What is the value of n?
ELEN [110]

Answer:

c. 85

Step-by-step explanation:

First, find the two angles of the triangle by doing this: 180-133=47 and 180-142=38. Then the last angle is 95 and you do 180-95 to get n which is 85.

Answer:

$11.43

Step-by-step explanation:

use a calculator and type in 76.25 + 15%, which will equal 87.68.

Then you subtract 76.25 from 87.68. 87.68 - 76.25 = 11.43.
