The first equation is

The second equation is

We want to eliminate y, so we multiply the first equation by



We now subtract equation (3) from (2)



Multiply both sides by



Substitute into the first equation to solve for x .

Multiply to obtain



Multiply both sides by 2.


The solution is

Answer: Option A. Line segment A
Step-by-step explanation: we know that
The height of the triangle must be perpendicular to the base of the triangle
so
In this problem
The segment A is perpendicular to the given height
therefore
The base is the line segment A
