Question

5. Three angles of a quadrilateral are equal. If the fourth angle is 105º find the magnitude
each of the equal angles.​

Answer 1

Step-by-step explanation:

3x+105=360

3x=255

each angle is 85

Answer 2

Answer:  let 3 equal angle be x

                so, 3x + 105 = 360

                     3x = 360 - 105

                    3x = 255

                    so, x = 255/3 = 85 degree.
