Answer 2

Given That

Angle 2=5x
Angle 1=4x

Angle 1 and 2 are on a straight line So,

$5x + 4x = 180$
$9x = 180$
$x = 180 \div 9$
$x = 20$
Therefore,

Angle 1
$= 4x$
$= 4\times 20$
$= 80$

Also

Angle2
$= 180 - 80$
$= 100$
Angle 1=80
Angle 2=100

Angle 1= Angle 3 =80
Angle 2= Angle 4=100

Also

Angle 4= Angle 6(Alternate Interior Angles)=100
Angle6=Angle8(Vertically Opp. Angles)=80

Angle3=Angle5(Alt Int Angles)=100
Angle5=Angle7(V.O.A.)=80

Angle1=80
Angle2=100
Angle3=80
Angle4=100
Angle5=80
Angle6=100
Angle7=80
Angle8=100
