Question

Ab is parallel to cd and angle 1 and 2 are in ratio 3 ratio 2 . Determine all the angles from 1 to 8​

Answer 1

Let angle 1 =3x and angle2=2x

Angle 1 and 2 are linear pair of angle

Now, angle1+angle2=180degree

or,3x+2x=180degree

or,5x=180degree

or,x=180/5

or,x=36degree

therefore,angle1=108degree and angle2=72degree

vertically opposite angles are equal

angle3=108degree(opposite to angle1)

angle4=72degree(opposite to angle2)

angle6=108degree(opposite to angle7)

angle5=72degree(opposite to angle 8)

corresponding angles

angle1=angle5=108degree

angle2=angle6=72degree
