What is the value of n? Write your answer as a number only

Hey there!

The value of "n" is 10.

Since the lines on the sides represent congruency of those 2 sides, we also know that angle T is equal to angle S. Since a triangle's angles add up to 180°, we can use the following equation, and solve:

180 = 3.5n + 3.5n + 11n       Add the "n"s

180 = 18n                              Divide both sides by 18

10 = n

Hope this helps! Good luck on your assignment! Have a great day!
