We are asked to find the length of

, which measures

. Using the segment addition postulate, we can add the two given expressions for

and

and make it equal to the expression for

.





We've found the value of

, but we aren't done yet. We need to plug in the value we got for

into the expression for

, which is

. Therefore,

. Hope this helped and have a great day!
