Answer 1

Alternate interior angles means the angles across from another are equal. If you follow the line up 85 is directly across from 2x+1
then you can say
85 = 2x +1
85 -1 = 2x
84 = 2x
84/2 = x
42 = x

supplementary angles make a straight line so they must add to equal 180 degrees.
That means the other angle 3y+5 = 180-85
3y +5 = 95
3y = 95-5
3y = 90
y = 90/3
y = 30

Answer 2

Alternate interior angles are formed by a transversal intersecting two parallel lines . They are located between the two parallel lines but on opposite sides of the transversal, creating two pairs (four total angles) of alternate interior angles. Alternate interior angles are congruent, meaning they have equal measure.
