Answer:130 degrees
Step-by-step explanation: Exterior angles should add up to 360. So add the exterior andles you have, 140+56+34=230. Then subtract the sum from 360 to find the missing exterior angle. 360-230=130.
The value of x is 130
The sum of the measures of the exterior angles of any triangle is 360 degrees.
We know,
sum of Exterior angles of polygon is 360.
So,
140 + 34 + 56 + x = 360
x= 360 -230
x=130
