Since J, P, and L are the midpoints of KH, HM, and MK, respectively, the values of x, y, and z are as follows;

x = 4.75

y = 6

z = 1

How to find the Centroid of the Triangle?

The centroid theorem states that the centroid of a triangle is located at two-third (2/3) of the distance from the vertex to the midpoint of the (opposite) sides.

The centroid of a triangle simply refers to the point where the three (3) medians of the triangle meet or intersect. By applying the centroid theorem to triangle KHM (ΔKHM);

Side HQ = (2/3)(LH)

y = (2/3)(3 + y)

3y = 2(3 + y)

3y = 6 + 2y

y = 6.

Side KQ = (2/3)(KP)

7 = (2/3)(7 + 2x - 6)

21 = 2(1 + 2x)

10.5 = 1 + 2x

2x = 9.5.

x = 4.75.

Side QM = (2/3)(JM)

4 = (2/3)(2z + 4)

12 = 2(2z + 4)

6 = 2z + 4

2z = 2

z = 1.

In the figure shown, if J, P, and L are the midpoints of KH, HM, and MK, respectively-example-1
