Textbook Problem

In Δ A B C , M is the midpoint of A B ¯ and N is the midpoint of A C ¯ . If MN= 3x-11 and BC= 4x+24, find the value of x. To determine

To Find:

Value of x.

Explanation

Given:

M is the midpoint of AB¯ and N is the midpoint of AC¯

Calculation:

The line joining the midpoints of two sides of a triangle is parallel to the third side.

Therefore

MN=12(BC)
