Firstly , we can draw diagram
we are given that
XYZ is equilateral triangle
so,
XY=YZ=XZ=6
and when we draw a line from X intersect at mid point between Y and Z
It will also be perpendicular line
so, we can use Pythagoras theorem

now, we can solve for h


so,

Answer:
IJ= 27
Step-by-step explanation:
HI+IJ=HJ
