1.

In the following figure if Lparallel to M and angle 1 is equals to 50° then angle 8 equals to​

Answer»

-step EXPLANATION:We can SEE that ∠1+∠4=180 o (Supplementary Angles)⇒∠4=180 o −∠1=180 o −50 o =130 o Now , as m∣∣n∴∠4=∠5 (Alternate Interior Angles are EQUAL between 2 PARALLEL lines)Hence, ∠5=130 o
