Answer:
C
Step-by-step explanation:
∠ 4 and ∠ 8 are corresponding angles
Each is in the same position (the lower left angle ) in its group of 4 angles.
(-13/2,3), use formula x2+x1/2,y2+y1/2
10*2/5= 20/5 = 4 = 4.0 where 4 is the unit.(whole number)
We know the full protractor measures 180 degrees.
We need to know what angle it is on. By looking at it, it looks like it is on 135.
180-135= 45
The angle is 45 <em>degrees.
