Question

one angle of quadrilateral is 111 degree and the reaming 3angles are equal find these angles​

Answer 1

The sum of interior angles of a quadrilateral = 360

angles are 111,x,x,x as other three are the same

So 111+x+x+x = 360

3x = 249

x = 83

So the other three angles of the quadrilateral are 83°

.....plzzz mark the answer as brainliest

Answer 2

Answer:

One angle of quadrilateral =111

And the rest 3 are equal so for rest 3 assume them as ' x ' because they all are equal.

A/q

3x+111=360 (Sum of angles of quadrilateral is 360)

3x=249

×=83

so each angle will be of 83 degree
