Two parallel lines l and m are cut by a transversal t. If the interior angles on the same side of the transversal t be 2x−9 and 3x−7 . Find the measure of each angle.
Given (2x−9) and (3x−7) are interior angles of the same side of the transversal .
we know that, sum of interior angles of same side of the
transversal =180∘
⇒2x−9+3x−7=180
⇒5x−16=180
⇒5x=180+16
⇒5x=196
x=1965
∴x=39.2
Therefore, 2x−9=(2×39.2)−9
=78.4−9
=69.4∘
3x−7=(3×39.2)−7
=117.6−7
=110.6∘
Hence, measure of each angle is 69.4∘ and 110.6∘
