Question

if AB || CD, CD || EF and Y : Z = 3 : 7 find x​

Answer 1

Step-by-step explanation:

x=180°-y

Now, y:z=3:7

3z=7y

Now 180°-y=z

180°=z+y=z+3z/7

180°*(7/10)=z

z=126°

Therefore, z=x

So, x=126°

Answer 2

Answer:

if y:z=3:7

3x+7x=180

10x=180

x=180/10=18

hence

y= 3x18=54

z=7x18=126

now

x+y=180

x+54=180

x=180-54

x=126
