Vertical angles
If the two angles are vertical angles, what is the value of x?

Answer:
17
Step-by-step explanation:
Vertically opposite angles are equal
so
7x - 9 = 110
7x = 119
x = 17
Answer:

OK so you have 7x-9 and you know that equals 110 so you simply work it out.
7x-9 = 110
+9 +9
7x = 119
_________
7 7
x = 17
