Answer 2

Solution :-

from image we can see that , line l is parallel to line m .

So,

→ (120° - x) + 5x = 180° { Angle between parallel lines on same side of transversal are supplementry. }

→ 120° - x + 5x = 180°

→ 120° + 4x = 180°

→ 4x = 180° - 120°

→ 4x = 60°

→ x = 15° (Ans.)

Note :- if angle is given (120° + x) and 5x ,

→ (120° + x) + 5x = 180°

→ 120° + 6x = 180°

→ 6x = 180° - 120°

→ 6x = 60°

→ x = 10° (Ans.)
