Answer:
u=30
x=150
z=150
y=30
Step-by-step explanation:
u=y [ being vertically opposite angle]
x+u=180[ being linear pair]
x+30=180
x=180-30
z=x[being vertically opposite angle]
y=u[ being voa]
=40°
Sorry that's all I know
^keep safe^
The answer should be B. 86.7
x = 9
60 + 6x + 16 = 13x + 13
6x - 13x = 13 - 16 - 60
- 7x = - 63
- x = - 63/7
- x = - 9
c = 117
d = 63
e = 63
