Question

Please answer me my questions and correct ​

Answer 1

Answer:

x = 70°, y = 110°, z = 120°, w = 60°

( all are linear pair )

so, x + y + z + w = 360°

Answer 2

Answer:

x+110°=180°[linear pair]

x=180°-110°

x=70°

y+70°=180°(linear pair)

y=180°-70°

y=110°

z+60°=180°(linear pair)

z=180°-60°

z=120°

x+y+z+w=360°(sum of exterior angles)

70°+110°+120°+w=360°

300°+w=360°

w=360°-300°

w=60°
