Answer:
Explanation:
You want to know the relationship between obtuse angle 2 and a given acute angle of 61° where a transversal crosses parallel lines.
Angle relations
Angle 1 and the angle marked 61° are corresponding angles, hence congruent. Angles 1 and 2 form a linear pair, so are supplementary. This means 61° and angle 2 are supplementary.
∠2 = 180° -61°
∠2 = 119°
