see the attached figure to better understand the problem

we know that

If a and b are parallel lines

then

m∠1=m∠4 --------> by alternate exterior angles

m∠3+m∠4= $180\°$ --------> by supplementary angles

so

m∠3+m∠1= $180\°$

therefore

<u>the answer is the option</u>

m∠1 = 110° and m∠3 = 70°
