Question

in the adjoining figure if line l || m , then find the value of x. (give reason)​

Answer 1

Step-by-step explanation:

according to the prblm

x°=r°[vertically opposite angles]

but in the figure we can see

r°+60°=180[exterior angles on the same side of transversal]

so r°=180_60

r=120

sox°=120° [vertically opposite angles]
