Question

3 angles of a quadrilateral are equal. If the fourth angle is 69 degrees. Find the measure of each angles

Answer 1

Answer:

total measure of interior angles =360

4th angle =69

sum of other three angles=360-69=291

measure if each angle=291÷3=97°

hope this helps .!!

Answer 2

Answer:

let x be the common angle of quadrilateral

there fore we know that sum of each angle of quadrilateral is 360°.

x+x+x+69= 360°

3x =360-69

x=291/3

x=97°

thus the measure of each of the angle is 97°
