Question

Q8. If AB is parallel to CD and EF is a transversal, then find x​

Answer 1

(7x - 12°) + (4x -17°) = 180° (Consecutive interior angles)

7x +4x -12° -17° = 180°

11x - 29° = 180°

11x = 180° + 29°

x = 219°/11

Answer 2

Answer:

x=19degrees

Step-by-step explanation:

hence, AB parallel CD and EF is transversal. the angles inside AB and CD are Co interior angles .

sum of Co interior angles is 180 degree.

A. T. Q.,

7x-12+4x-14=180

11x-29=180

11x=180+29

11x=209

x=209/11

x=19
