Question

The ratio of measures of two interior angles, formed by two parallel

lines and their transversal, is 5:4. Find the measure of each of the interior

angle.​

Answer 1

Answer:

100° and 80° is the correct answer

Answer 2

Answer:

Ratio of two interior angles = 5 : 4

First angle = 5x°

Second angle = 4x°

As we know that sum of interior angles on same side of transversal intersecting two parallel lines = 180°

( First angle + Second angle ) = 180°

( 5x° + 4x° ) = 180°

9x° = 180°

X = 180/ 9

X = 20°

First angle = 5x

= 5 × 20

= 100°

second angle = 4x

= 4 × 20

= 80°
