Angle one is a angle pair with the angle value of 70 degrees. This means that angle one has to be the supplement of 70 degrees (180-70), which is 110 degrees.
Angle 2 is an alternate interior angle pair with 70 degrees, which means that the angle is the same as the 70 degree angle.
Angle 3 is vertical angle to angle 2, so that means angle 3 is 70 degrees.
