Answer:
120 degrees.
Step-by-step explanation:
This is a pentagon so the interior angles add up to 540 degrees, so we have:
4x + 4x + 4x + 3x + 3x = 540
18x = 540
x = 30 degrees.
So m < C = 4*30 = 120 degrees.

Answer:
17/9 or 1 8/9 if you are looking for a mixed fraction
Step-by-step explanation:
1 7/9 + 4/36
16/9 + 4/36
Multiply 16/9 by 4/4 to get the same denominator as 4/36
64/36 + 4/36
68/36 = 17/9 = 1 8/9
