Answer:
Yes.
Step-by-step explanation:
If a graph G doesn't have a circuit, we must have that
where 
is the number of edges of the graph and 
the number of vertices. However, in this case it holds that
-5
a^2-25=0
a^2=25
take the square root of both sides
a=5, and -5
Answer:
108
Step-by-step explanation:
Hey There!
So the arc is equal to its corresponding angle
We are given the angle of KL which is 30 so all we need to do is find the length of arc JK
The angles given and the missing angle are supplementary angles meaning that they will add up to equal 180
so we subtract the given angles from 180 to find the missing angle
180-30-72=78
Now we just add arc JK and arc Kl
30+78=108
so arc JL is equal to 108
question no 39 isnot correct. they should be in i j k form
