Answer:
x = 140
Step-by-step explanation:
let the other unknown angle be y
y = 180 - (70+60)
= 50
x + x + 30 + y = 360
=> 2x + 80 = 360
=> 2x = 360-80
2x = 280
x = 140

Answer:
in this figure you can find D and C by linear pair
Step-by-step explanation:
so D= 180- 70 that's 110
C = 180-60 that's 120
then by the property of polygon sum of all angles = 360
so, 30+120+110+x+x = 360
260 + 2x = 360
2x= 360-260
2x=100
X= 100/2
X = 50
