Answer:
1)x=60°
2)DEF=DCG=70°
3)(i)not parallel (ii) parallel
4)AOC=132°
5)ABC=55°
6)x=30
Step by step explanation:
1) x+2x=180
3x=180
x=60
3) if the 2 lines are parallel the sum of the interior angles should be 180
(i) 126+44=170 .....not parallel
(ii) 57+123=180........parallel lines
4) draw a perpendicular line form A to C
such that BAC =90 & DCA=90
Then in triangle AOC,
AOC+OCA+CAO=180°
AOC +(120-90)+(108-90)=180
AOC=180-(30+18)
AOC=180-48
AOC=132°
5) according to the diagram ACE=60°
ACB=180-(60+65)
=180-125
=55°
6)4x+2x=180
6x=180
x=180/6
x=30°
Hope u understand!!
