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!

the answer to the expression is 83

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
