Answer 1

Answer:

300°

Step-by-step explanation:

x and angle ABC are supplementary angles so

x+ABC=180°

x+110°=180°

x=70°

y and angle BCD are supplementary angles so

y+BCD=180°

y+130°=180°

y=50°

z and angle CDA are supplementary angles so

z+CDA=180°

z+70°=180°

z=110°

as per observation

AD | | BC

x=w

x+y+z+w

70°+50°+110°+70°

300°
