Sign In
The Triangle Midsegment Theorem tells us that, if a segment joins the midpoints of two sides of a triangle, then the segment is half as long as the third side.
x=12
To find the value of x in the given diagram, let's start by labeling the vertices of each of the smaller triangles.
XY= 3x, AC= 5x+12
LHS * 2=RHS* 2
LHS-5x=RHS-5x
