Method 1
Angle 3 = 65 degrees . . . . . . . . (corresponding angles are equal)
Angle 1 =180 - 65 = 115 degrees . . . . . . . .(angles on a paralel line are suplementary)
Method 2
Angle 2 =180 - 65 = 115 degrees . . . . . . . .(angles on a paralel line are suplementary)
Angle 1 = 115 degrees . . . . . . . . (corresponding angles are equal)
The measure of angle 1 is 115 degrees.
