Textbook Problem

In Exercises 29 to 31, M and N are the midpoints of sides R S ¯ and R T ¯ of R S T , respectively.

Given: M N = x 2 + 5
  S T = x ( 2 x + 5 )
Find: x , M N , S T

To determine

To find:

x, MN, and ST

For MN=x2+5

ST=x(2x+5)

Explanation

Calculation:

Given,

MN=x2+5

ST=x(2x+5)

M and N are the midpoints of sides RS¯ and RT¯ of RST, respectively.

A line segment that joins the midpoints of two sides of a triangle is parallel to the third side and has a length equal to one-half the length of the third side.

Thus,

MN=12ST

x2+5=12·x(2x+5)

Multiply; by 2 on both sides,

2(x2+5)=2·12·x(2x+5)

2(x2+5)=x(2x+5)

Apply the distributive property of multiplication over addition to the left and right of the above equation
