Answer:
Let the unknown value be x
Angles = 2x , 3x
2x + 3x = 180 (Since, Co-interior angles are supplementary)
5x = 180
x = 180/5
x = 36
angles are 72 and 108 degrees

Given: Two co interior angles on the same side of a transversal interacting two ||'s lines are in the ratio of 2:3.
Need to find: The two angles.
❍ Let the first angle be 2x and second angle be 3x respectively.
⠀⠀⠀
⠀⠀⠀⠀
⠀
- Sum of Interior angles on the same side of a transversal intersecting two ||'s lines is 180°.
⠀
Therefore,
⠀
⠀
Hence,
⠀
- First angle, 2x = 2(36) = 72°
- Second angle, 3x = 3(36) = 108°
⠀
