Question

three angles of quadrilateral are equal 4th angle is 120 .find the measure of each equal ​

Answer 1

Answer:

let the angle be x° each

and fourth question is 120° ( given)

since

, sum of all angles of a quadrilateral is 360°

so,

x + x + x + 120 = 360°

=> 3x = 360 - 120°

=> 3x = 240°

=> x = 240/3

=> x = 80°

so,

each of the three equal angles are 80°...

Answer 2

Answer:

80 is your answer

Step-by-step explanation:

3x+120=360

3x=360-120

3x=240

x=80

Hope you get your answer
