m∠2=m∠1

m∠2=105°

m∠1=75°

m∠3=m∠1

Answer 1

Okay so the first one is right.
The second one is wrong.
the third one is right.
The forth one is wrong.

Answer 2

∠1 and 105° are supplementary angles. (supplementary = 180°)

180 - 105 = 75°

∠1 = 75°

∠1 and ∠2 are corresponding angles, and so there measurements will be the same

∠1 = ∠2
∠1 = 75°
∠2 = 75°


105° and ∠3 are same side, and are corresponding angles. Therefore, ∠3 = 105°

m∠1=75°

180° (the measurement of a straight angle).

Subtract the 105° (given) from the straight angle

180 - 105 = 75

m∠1=75°

hope this helps
