Answer:
Option B is correct.i.e.,
Step-by-step explanation:
Given: Pyramid with equilateral triangle as base
Length of side of equilateral triangle = s unit
to find: height of equilateral triangle
Here we use a property of equilateral triangle.
Perpendicular from a vertex on a side and median of that side of a triangle is same in equilateral triangle.
All heights are of equal length. So, we just need to find one height or length of 1 altitude.
Figure of base triangle is attached
In Δ ABC
AB = BC = AC = s unit
AD is height
BD = 
Now, In Δ ABD
using pythagoras theorem
BD² + AD² = AB²








Therefore, Option B is correct.i.e., 
The solution is x=6 and y=5

<em>Additional comment</em>
One of the "test-taking skills" that you need to learn is that <em>multiple-choice answers that make false statements can be immediately rejected</em>. (You don't even need to check to see if they answer the question.)
Of course, there are occasional questions that ask you to find the <em>false</em> statement on the list. In those cases, you reject the <em>true</em> ones.
