Answer:
7x° = 70°
y° = 40°
z° = 140°
Step-by-step explanation:
70°+ (7x°+4x°)= 180°
70°+ 11x°= 180°
11x°= 180°-70°
11x°= 110°
x°= 110/11
= 10°
7x°=7×10
= 70°
7x°+ 70° + y°= 180° [Angle Sum Property]
70°+ 70°+ y°= 180°
y°= 180°-70°- 70°
= 40°
y°+z°= 180° [Linear Pair]
40°+z°= 180°
z°= 180°-40°
= 140°
