Question

Lines l || m; tis a transversal. Find the measureofz(2)(Mention reasons)

Answer 1

Answer:

If Line L parallel to M,and T is a transversal

then

60+z=180°

As we know

in two parallel lines,if co interior angles or interior angles on the same side of the transversal are available,then they are supplementary,that is their sum is 180°

Hence

60+z=180

z=180-60

z=120°

thus value of z=120°

Let's check whether it's correct or not

z+60=180

120+60=180

180=180

L.H.S=R.H.S

hence verified
