Question

In the above fig,if AB||CD,CD||EF and y:z = 3:7 ,find x with the solution​

Answer 1

Answer:

x= z= 126

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=10180∘=18∘

z=7×18∘=126∘

x=z=126∘

If the answer helps u then plz mark me as brainliest.....thank u
