Question

If two interior angles on the same side of the transvarsal intersecting two parallel lines are in the ratio5:4 then the smaller of the two angles​

Answer 1

Answer:

Let the angles be 2x and 3x

Now sum of interior angles on same side of transversal intersecting two parallel lines is 180

∘

⇒2x+3x=180

∘

⇒5x=180

∘

⇒x=36

∘

So the angles are

2x=2×36

∘

=72

∘

3x=3×36

∘

=108

∘

So the smaller angle is 72
