Answer:
103
Step-by-step explanation:
To solve this you first have to find the complement to he 110 degree angle (z). You do this by subtracting 180-110 to get z=70 degrees. Next, because its a four sided figure you know the total angle sum should equal 360. Therefore, 360-100-87-70=angle y. Angle y= 103 degrees. Hope this helps
