Step-by-step explanation:
2y+10+50°+40°+130°= 360°(the sum of angles around a point is 360°)
2y+230°=360°
2y= 360°-230°
2y = 130°
y= 130°/2
y= 65°

Answer:
y =65
Step-by-step explanation:
(2y+10°)+50°+40°+130°=360 (because angle sum property)
remove the brackets (2y+10°)
=2y+230°=360° (add all the angles)
=2y=360°–230°
=2y=130°
=y=130°/2
=y=65°
