56y^2-49y+46y
56y^2-3y
tada

Answer:
1, 5, 8
Step-by-step explanation:
1 is a vertical angle with angle 4, so is congruent.
5 is an alternate interior angle with angle 4, so is congruent.
8 is a corresponding angle with angle 4, so is congruent.
If A represents an angle, its complement is 90-A.
If m<1 = 36, then its complement is 90-36 (degrees), or 54 (degrees).
