They are parallel to each other
Answer:
<em>I've attached a picture of a unit circle with the quadrant labeled. </em>
<u>Calculate the degree of 5п 8 radians:</u>

<u>Locate the general location of 112.5° on the unit circle:</u>
It's between 120°(
) and 90°(
).
<u>Find the quadrant it lies in:</u>
Quadrant II
Du to the triangle is an Equilateral triangle, both angles are equal.
Now we have a straight angle RTU which equals 180 degrees so,
<RTS + <STU = 180
5x + 5x -30 = 180
10x = 210
x = 21
