Question

in fig ab is parallel to CD and angle one : 4 is equal to 3:2. find Angle 6.

Answer 1

3x+2x=180. (linear pair)
5x=180
x=36
$< 1 = 108$
angle4=72
angle1=angle6. (alternate exterior angle)
angle6=108

Answer 2

Answer:

L1+L4=3:2

let the angle be x:

3x+2x=180(linear pair)

5x=180

x=180/5

x=36

hence:

L1=(3X36)=108

L4=(2X36)=72

(proving:L1+L4=180

108+72=180

Hence proved!!)

L1=L6 (Alternative Exterior Angle property)

L6=108

I hope it helps you
