Hi!
Your answer is C.
The vertex is the point where two different rays meet, forming an angle.
It can also simply be the point where 2 straight lines simply meet.
Option A is NOT correct because a vertex is not angle, it is a <em>part </em>of an angle.
Option B is NOT correct because, if there's only one segment, we cannot form a vertex.
See the image below for an example:

Answer:
Hello your question is incomplete below is the complete question
option B is correct
f(x) = 1 if x ≤ 0
-2 if x > 0
Step-by-step explanation:
The Rule of the piece-wise-defined function is :
from the given figure attached it can be seen that as : x ≤ 0 , y = 1
while for x > 0 , y = -2
therefore option B is correct
f(x) = 1 if x ≤ 0
-2 if x > 0
<em>a = 30°</em>
<em>b = 70°</em>
<em>c = 80°</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em />
<em>a ; b ; c = angles</em>
<em>a + b + c = 180°</em>
<em>b + c = 5a</em>
<em><u>replace (b + c)</u></em>
<em>a + (b + c) = 180</em>
<em>a + 5a = 180</em>
<em>6a = 180</em>
<em>a = 30°</em>
<em />
<em>b + c = 180 - a</em>
<em>b + c = 150</em>
<em>c = b + 10</em>
<em><u>replace c</u></em>
<em>b + (b + 10) = 150</em>
<em>2b = 150 - 10</em>
<em>2b = 140</em>
<em>b = 70°</em>
<em>c = b + 10</em>
<em>c = 80°</em>
<em>Good luck !</em>
