The terminal arm of an angle drawn in standard position rotates in a positive direction through two quadrants of the coordinate
miskamm [114]
There are 4 quadrants and each quadrant is has a measure of 90° angle.

Because the direction is positive, it means that the arm is going from 1st quadrant to 2nd quadrant.

90° + 90° = 180°

Because there is an additional rotation of 25°, the arm is now in the 3rd quadrant. 

180° + 25° = 205°

The measure of the angle is 205°

What value of x makes the
loris [4]

Answer:

x = -12

Step-by-step explanation:

<u>Step 1:  Add 1/4x to both sides</u>

-\frac{1}{4}x - 12 = x + 3

-12 - \frac{1}{4}x + \frac{1}{4}x = x + 3 + \frac{1}{4}x

-12 = \frac{5}{4}x + 3

<u>Step 2:  Subtract 3 from both sides</u>

-12 - 3 = \frac{5}{4}x + 3 - 3

-15 = \frac{5}{4}x

<u>Step 3:  Multiply both sides by 4/5</u>

-15*\frac{4}{5}=\frac{5}{4}x * \frac{4}{5}

-12 = x

Answer:  x = -12
