Question

pls tell me the answer pls give me the answer in detail pls ​

Answer 1

1. x=y+90/3

x=y+30

as it is a straight line so,

x+y=180°

y+30+y=180

2y=150

y=75

x=105

2. figure is wrong or in complete

3. add all angle and make it = to 360

4.figure not proper

5. let one angle be x so second angle would be

3x + 20

they are supplementry

x+3x+20=180

4x=160

x=40

second angle =120+20=140
