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 .
