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

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:
