Answer:
Step-by-step explanation:
1) AE // AC and EB is transversal
2x+ 6x = 180 {Co-interior angles are supplementary}
8x = 180
x = 180/8
x = 22.5
2)8x + ∠CAB = 180 {Linear pair}
∠CAB = 180 - 8x
9x + ∠ABC = 180 {linear pair}
∠ABC = 180 - 9x
∠CAB + ∠ABC + ∠ACB = 180 {Angle sum property of triangle}
180 - 8x + 180 - 9x + 5x = 180
-8x - 9x + 5x = 180 - 180 - 180
-12x = -180
x = -180/-12
x = 15
