Find the angle adjacent to the ABC angle if 1) ABC angle = 36 degrees; 2) Angle ABC = 102 degrees

Two adjacent corners together form an expanded angle equal to 180 °, therefore, if these angles are added together, we get an expanded angle or 180 °. To find the adjacent angle, subtract the value of the other angle from the value of the expanded angle (180 °).
180 – 102 = 78 °.
