Question

Find the value of x in each of the following figure if l is parallel to m

Answer 1

Answer:

case 1 80°

Case 2 100°

Case 3 60°

Answer 2

Answer:

i. 100°

ii. 60°

iii. 100°

Step-by-step explanation:

(i)x=100° (alternative pairs of angle)

(ii)x+2x=180° (co-interior angle)

3x=180°

x=180°/3

x=60°

Hence, x=60° and 2x=2×60=120°

(iii)x=100° (alternative pairs of angle)
