Answer:
y = 4x - 8
Step-by-step explanation:
x = 1/4y + 2
-1/4y -1/4y
-1/4y + x = 2
-x -x
-1/4y= -x + 2
*-4 *-4
y = 4x - 8
The angle of 110° and the angle labelled as 1 form 180°, so we have

The same holds for the angle labelled 2 and the 115° angle:

Angle 1, 2 and 7 are the interior angles of a triangle, so they sum to 180. We can deduce

Angles 5 and 7 are corresponding angles, so they have the same measure.
