Question

One angle of a quadrilateral is 111° and the remaining three angles are equal. Find three Angeles.

Answer 1

MARK ME AS THE BRAINLIEST

Answer:

let us assume the three equal angles as x

we know that,

111° + x + x + x = 360° (angle sum property of a quadrilateral)

111° + 3x = 360°

x = 360-3/111

= 3.21° (approx)

HOPE IT IS CORRECT

Answer 2

Hyy Dude

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 degree

May this helps you
