Since these angles are vertical they are equal to one another. So we can write 6a + 10 = 3a + 55. To solve we subtract 3a from both sides and we get:

3a + 10 = 55, then we subtract 10 from each side: 3a = 45 and finally we divide both sides by 3 and get a = 15. Now that we know a we can plug it into one of the angles and just solve the statement. 6(15)+10 which gives us 100 for the measure of the angle.

Clara created a coordinate grid of her city. The bowling alley is located at (10, 12) and the skating rink is located at (-6, -4
yulyashka [42]

First we need to know the coordinates of the movie theater, we can do this applying the midpoint formula:

\begin{gathered} P(BA,SR)=(\frac{10-6}{2},\frac{12-4}{2})\text{ = (}\frac{4}{2},\frac{8}{2}) \\ \Rightarrow P(BA,SR)=(2,4) \end{gathered}

We have that the movie theater is located at (2,4). Now we use this coordinates to find the location of Clara's house using again the midpoint formula:

\begin{gathered} P(MT,SR)=(\frac{-6+2}{2},\frac{4-4}{2})=(-\frac{4}{2},0) \\ \Rightarrow P(MT,SR)=(-2,0) \end{gathered}

Therefore, Clara's house is located at (-2,0)

A certain connected graph has 68 vertices and 72 edges. Does it have a circuit?
OLEGan [10]

Answer:

Yes.

Step-by-step explanation:

If a graph G doesn't have a circuit, we must have that

|E(G)|=|V(G)|-1

where |E(G)| is the number of edges of the graph and |V(G)| the number of vertices. However, in this case it holds that

|E(G)|=72>68=|V(G)|.
