In the figure shown line l and m are parallel. find the measure of each numbered angles

Angle 1= 180-111 =69 degree
angle 2=1 so ,69 degree(vertically oppsite angle)
angle 3= 180-111= 69 degrees(corresponding angle to 111 degree)
angle angle 6 =108 (vertically opposite angle)
angle 4 =108(corresponding angle)
angle 5=180-108 =72 (alternate angle)

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
