Question

in figure two straight lines ab and CD intersect each other o. in find the value of X ,Y and Z​

Answer 1

Step-by-step explanation:

we make three equations:.

1)84+2y+x=180

2)y+2z=180

3)2z+x=180

now by solving equation 2and 3

we get,

y+2z=2z+x

y=x

now solve equation 1)

84+2y+y=180

84+3y=180

3y=180-84

3y=96

y=32

now finding other unknown

according to equation 2)

y+2z=180

32+2z=180

2z=180-32

2z=148

z=74

y=x=32

Answer 2

Answer:

AB =180(A sum of a straight line =180)

y + 84 + 2y =180

y + 2y =180 - 84

3y = 96

y = 96 % 3

y = 32

Therefore angel AOD or y =32

Angel BOE = 2y

2*y

2*32

64

CD = 180 (A sum of a straight line = 180)

32 + 2z = 180

2z =180 - 32

2z = 148

AB = 180

148 + x = 180

x = 180 - 178

x = 32
