Question

# The angles in a rectangle are given by (x+30)∘ and (y+50)∘ respectively, find the value of x+y  90° 100° 80° 20°

Solution

## The correct option is B 100° We know that in a rectangle, all angles are equal to 90∘. So, the angles (x+30)∘ and (y+50)∘ need to be equated to 90∘ respectively. This gives us the following equations: (x+30)∘=90∘ and (y+50)∘=90∘  Solving these equations, we get x=60∘ and y=40∘ respectively and therefore, x+y=100∘.
