Answer:
measure of angle 5 = 75 degrees
Step-by-step explanation:
given measure of angle 8 = 105 degrees,
angle 8 and angle 5 are in a linear pair so,
(the sum of angles in a linear pair is 180 degrees)
therefore, angle 8 + angle 5 = 180 degrees
therefore,. 105 + angle 5 = 180 degrees
angle 5 = 180 - 105
angle 5 = 75 degrees
