Question

Find the measure of 43. <3 75 43 = [?]

Answer 1

Answer:

both are parallel to each other will make same angle 75 is correct

Answer 2

THEOREM:

Same Side Interior Angles Theorem:– If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.

ANSWER:

By same side interior angles theorem,

∠3 + 75° = 180°

∠3 = 180° - 75°

∠3 = 105°.
