Question

x=30 calculate the valve of y ​

Answer 1

Answer:

3y + 2x= 180° {linear pair of angles}

x=30

3y + 2(30)=180

3y+60=180

3y=180-60

3y=120

y=120/3

y=40°

Answer 2

Answer:

3y+2x=180°

since x=30 is given..

so, 3y+2(30) =180°

3y+60=180°

3y=180-60

3y=120°

y=120/3

y=40°

hence your answer is 40°
