2. Measuring and Constructing Segments

Continue to next subchapter

Exercise 8 Page 390

Using the Segment Addition Postulate, we can calculate the length

J L

by adding

J K

and

K L .

This is because the point

K

lies between

J

and

L .

J L = J K + K L

Let's use the given values of

J L

and

J K

to find the length.

J L = J K + K L

$J L = 144$ , $J K = 37$

144 = 37 + K L

$LHS - 37 = RHS - 37$

107 = K L

Rearrange equation

K L = 107

Therefore, the length

K L

is

107 .
