Question

In the adjacent figure AB||CD;CD||EF and y:z=3:7, find x

Answer 1

Step-by-step explanation:

Let y and z be 3u and 7u

∠x=∠z (Alternate angles)

∠x+∠y=180

∘

(Angles made on same side of transversal)

Put x=z

∠z+∠y=180

∘

7u+3u=180

∘

10u=180

∘

u=

10

180

∘

=18

∘

z=7×18

∘

=126

∘

x=z=126
