Answer: a= 144. b= 67
Step-by-step explanation:
Angle b and the angle of measure 113 are same side interior angles which sum to 180 (When 2 parallel lines are cut by a transversal, special angles are formed)
113+b=180. Subtract 113 from both sides.
b= 67 degrees
Now that you have b, the interior angles of four sided figures sum to 360.
a+113+67+36=360. Combine like terms.
a+216=360. Subtract 216 from both sides.
a= 144 degrees
