We know that sum of the angle of a quadrilateral is equal to 360∘360∘
Given :
Three angles are equal
Let the equal angle be x
3x + 6=360
3x=300
x=100
hence the equal angles are equal to 100 degrees

Answer:
Let x be the 3 equal angles.
We know,
Sum of all the quadrilateral is 360 degree.
so,
X + X + X + 60 = 360
3x + 60 = 360
3x = 360 - 60
3x = 300
X = 300/3
X = 100
thus, the measure of each of the equal angles is 100 degree .
