Answer:The value of angle y is 40°.
Complementary angles are the angles that have their sum equal to 90°.
Therefore, based on the information given, the value of angle y will be calculated thus:
x + y = 90°.
4y - 110° + y = 90°
Collect like terms
4y + y = 90° + 110°
5y = 200°
y = 200/5
y = 40°
The value of angle y is 40°.
