Alright, so since 6 and 3 are opposite, they are the same = 110 degrees. Next, since lines m and l are parallel, angle 3 and angle B (or at least the spot where B is at across from 1) are corresponding. Since a line is 180 degrees, we have 180-110=angle 1=70 degrees. Additionally, since the triangle is isosceles and angle 1 as well as angle ACB are across from both congruent sides, we can say that angle 1=ACB=70 degrees
