Question

please give me answer step wise I will mark you as brainleast​

Answer 1

Answer:

angle FOE=angle BOC

angle AOB=angleEOD

angleDOC=angleAOF

reason : vertically opposite angle

the sum of all the angles are equal to 360 degree.

so,

6y +6y+8y+8y+4y+4y=360

36y=360

y=360/36

y=10

I hope this was correct answer

Answer 2

Answer:

ANGEL AOB= ANGLE EOD =6y ( VERTICALLY OPPOSITE ANGLES

NOW WE WILL FIND THE LINEAR PAIR ,

ANG. FOE + EOD + COD = 180 BY LINEAR PAIR

4Y + 6Y + 8Y = 180

18Y = 180

Y = 180/18

Y = 10

SUBSTITUTE THE VALUES

AND WE WILL GET ANG. FOE= 40, ANG.EOD = 60 , ANG.COD = 80

SIMILARLY AOB ALSO BECOMES 60

USING LINEAR PAIR AGAIN

BOC + COD + EOD = 180

BOC + 80 + 60 = 180

BOC + 100 = 180

BOC = 80

NOW USING THE LINEAR PAIR AGAIN

BOC + AOB + FOA = 180

80 + 60 + FOA = 180

FOA + 140 = 180

FOA = 40
