Thre are two possible solutions, with the third vertex to the right or left of the y axis. The side length is obviously 4 and the base is along the y axis.
The y value of the third vertex is +2 .
For the x value,
x^2 + 2^2 = 4^2 (The square of the length of a side)
x = + or - sqrt 12
Okay I get everything but the
For the x value,
x^2 + 2^2 = 4^2 (The square of the length of a side)
x = + or - sqrt 12
How did you get that and why??
