Answer:
1=87° and 2=93°
Explanation:
A transversal has cut a pair of parallel lines.When a transversal cuts a pair of parallel lines different angles like alternate angles,corresponding angles,VOA and cointerior angles are formed whereas VOA,alternate angles and corresponding angles are equal and cointerior angles sums to 180°....
In the figure,
1=87 (being alternate angles)
And,
2+87°=180°
therefore,
2=93°
