Question

It is given that the difference between angle1and angle2 is 120 degrees. Write the measures of all four angles:

Answer 1

Answer:

30,150,30,150

1,3= 150 and 2,4=30

Step-by-step explanation:

Angle 2 = angle 4 = x (say)

angle 1 = angle 3 = y

2x + 2y = 360

=> x+y=180

also y-x=120

Adding both 2y =300

=> y= 150

=> x = 30

Answer 2

Answer:

150,30

Step-by-step explanation:

Use the fact that ∠1+∠2=180°, and ∠1−∠2=120°

2 ∠1 = 120+180

x = 150
