Question

Three angles of a quadrilateral are equal .If the fourth angle is 69 degree , find the measure of equal angles

Answer 1

let the three angles be x
thus
x+x+x+69=360
3x=291
x=73 degree

Answer 2

Answer:

Step-by-step explanation:

Let the angles be x

We know, sum of all angles in a quadrilateral are 360

Therefore, x+x+x+69=360

X= 97

Therefore the measure if the angles are 97 degrees
