Answer:
105.5 degrees
Step-by-step explanation:
Quadrilaterals always equal 360 degrees total
You already have 101 degrees + 48 degrees = 149 degrees
So take the 149 degrees away from 360 degrees: Now you have 211 degrees
Angles 1 and 2 have the same angle, as indicated by their matching line
So divide 211 degrees by 2, which = 105.5 degrees
