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:
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
