Answer:
A.) 10
Step-by-step explanation:
So draw the points on a graph is the best way to solve the problem, but if you can't then you have to mentally imagine it.
on the X axis B is 5 and C is 11 so the distance or length of the line between the points is 11-5=6
on the Y axis B is 2 and C is -6 so the distance or length of the line between the points is 2-(-6)=8
now you have two lines that can make a right triangle and use the Pythagorean theorem to solve for the long line connecting directly from point B to point C +
=
so
+
=100=
, z=
=10
