Answer:
∠1 = 73
∠2 = 107
∠4 = 107
Step-by-step explanation:
∠1 and ∠3 are vertical angles
Vertical angles are congruent
Which means that because ∠3 = 73°, ∠1 also equals 73°
∠2 and ∠3 are supplementary angles
supplementary angles add up to equal 180
Thus, ∠2 + ∠3 = 180
If ∠3 = 73° then ∠2 + 73 = 180
180 - 73 = 107
Hence, ∠2 = 107
∠2 and ∠4 are vertical angles
Like stated previously vertical angles are congruent
Which means that because ∠2 = 107°, ∠4 also equals 107°
