I do not understand the process/steps to do this. ​
VARVARA [1.3K]

Answer:

Step-by-step explanation:

Remark

An angle bisector sets up a triangle ratio that looks like the following proportion.

3x - 3               5x

======   =      ======             Cross multiply

24                     44    

44*(3x-3) = 24*5x                 Remove the brackets on the left

132x - 132 = 24*5x               Combine the right side

132x - 132 = 120x                 Add 132 to both sides

132x = 120x + 132                Subtract 120x from both sides

132x- 120x = 132                  Combine

12x = 132                              Divide by 12

x = 11
