monitta

Answer:

x:

5x - 29 = 3x+ 19

2x = 48

x = 24°

Angle 1:

180 - (3x+7) = 180 - 79 = 101°

Angle 2:

3x + 7 = 79°

Angle 3:

Same as Angle 1 = 101°

Angle 4:

Same as Angle 1 = 101°

Angle 5:

Same as Angle 2 = 79°

Angle 6:

Same as Angle 5 = 79°

Angle 7:

180 - (5x - 29) = 180 - 91 = 89°

Angle 8:

Same as Angle 7 = 89°

Angles 2 and 3 are Supplementary angles
