Solution

## The correct option is C No extra information is necessary and x+y=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∘.
