Answer:
60 degrees
Step-by-step explanation:
a+b+c= 180 degrees therefore 5x + x + 3x = 9x
9x=180 (divide) --> x=20
since c = 3x substitute in 20 for x --> 3(20) = 60 degrees for angle c

Answer:
i can see the actual question, what is it?
Answer:
n = 28 degree
Step-by-step explanation:
2n + 17 + 2n - 5 + 2n = 180 degree (sum of interior angles of a triangle)
6n +12 = 180
6n = 180 - 12
n = 168/6
n = 28 degree
