To  find the height of the triangle draw a perpendicular bisector from the top of the triangle to the base.

Now we 2 right triangles with base 8m  and side 16m and height will be the length of the perpendicular line.

Using Pythagoras theorem,

what are ur choices?

answer: y=0 if that is what u r looking for
