Find the angle measures. Justify your responses. Given: a||b, m∠6=128 Find: m∠1,m∠3

Line b is a straight line which is 180 degrees.

Angle 5 plus angle 6 need to equal 180

Angle 5 = 180 - 128 = 52

Angle 1 is the same as angle 5 because they are located in the same place on a straight line.

Angle 1 = 52 degrees.

Angle 3 is a vertical angle to angle 1, which means they are identical so angle 3 is also 52 degrees.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
