Question 1039308: Triangle ABC has its coordinates at A(a,-3), B(9,-3) and C(6,5). If the base is twice the height, find a.

The height is 5 --3 = 8
So the length of the base is 16
From the point B we can move left 16 or right 16.
Left 16 takes us to -7
Right 16 takes us to 25
So the two possible values for a are -7 and 25
We could have A(-7,-3) or A(25,-3)
