Question

One angle of a quadrilateral is 123° and the remaining three angles are equal. Find three angles.

Answer 1

Answer:

79,79,79

Step-by-step explanation:

other three angle are x,x,x

sum of all angles of quadrilateral are 360°

x+x+x+123=360

3x+123=360

3x=237

x=237/3

x=79

other three angles are 79,79,79

Answer 2

Step-by-step explanation:

sum of interior angles of quadrilateral is 360

step1 one of the angle is 123 .

• let the other be x,x,x

123+x+x+x=360

123+3x=360

3x=360-123

3x = 237

x =237/ 3

x=79
