Question

in figure AB||CD determine angle x
​

Answer 1

Answer:

285 degree

Step-by-step explanation:

draw a line to AB which divides x into two

name them as angle 1 and angle 2

40 degree+ angle 1= 180 ( co interior angle)

angle 1= 180-40

angle 1=140 degree

35 degree + angle2=180 ( co interior angle)

angle 2= 180-35

angle 2= 145 degree

x= angle 1+ angle 2

x= 140+145

x = 285

hope it helps you

Answer 2

Answer:

x = 140

Step-by-step explanation:

Given- angle A = 108

angle C = 112

To find- the value of x

Construction- join EF , angle FEC mark as angle 1 , angle FEA mark as angle 2

Proof- angle 1 + 112 = 180.........1

angle 2 + 108 = 180.........2

add both the equation

angle 1 + 112 + angle 2 + 108 = 180 + 180

angle 1 + angle 2 + 220 = 360

x + 220 = 360

x = 360 - 220

x = 140
