Can someone help me with this step by step if you can please

Answer:
The answer to your question is: 45°
Step-by-step explanation:
Angle 1 and angle 2 are supplementary angles so the sum oficina them equals 180°.
Angle 1 + angle 2 = 180
Angle 2 = 180 - 135
Angle 2 = 45°
Answer:
∠2=45°
Step-by-step explanation:
If you look at ∠1 and ∠2, it is half of a parallelogram. This means that ∠1 and ∠2 have to equal 180°.
180°-135°=45°
