Question

in the figure the three concurrent lines AB, CD and EF are intersecting at 'O'. then 'Y' value.

plz answer step by step. ​

Answer 1

Given ,

• the three concurrent lines AB , CD and EF are intersecting at the point " o "

Find ,

• ' Y ' value

Now ,

• AB = 2y = 180°
• ==> y = 180 / 2
• ==> y = 90

• CD = 6y = 180°
• ==> y = 180 / 6
• ==> y = 30

• EF = y = 180°
• ==> 180/y
• ==> 180

Therefore ,

• y + 2y + 6y
• 180 + 2(90) + 6(30)
• 180 + 180 + 180
• 360°

• y = 360°

Answer 2

Answer:

y=20

Step-by-step explanation:

if ab and ef are intersecting at o then

angle EOA = angle BOF ....(vertical opposite angles are equal)

then CD is a straight line so sum of all angles on that line will be 180

therefore y+6y+2y=180

9y=180

therefore y=20

thank you
