Question

if one of a qudairateral is 120°and the remaining angels are equal,find all the other angels​

Answer 1

Answer:

80

Step-by-step explanation:

3x + 120=360

3x = 360-120

3x = 240

x = 240/3

x=80

Answer 2

Answer:

consider each equal angles as x

[tex]120 + x + x + x = 360 \\ 120 + 3x = 360 \\ 3x = 360 - 120 \\ 3x = 120 \\ x = \frac{120}{3 }

so each equal angles is equal to 40°
