I don't see the side lengths in your message. To find angle C you can use the inverse tangent with the side opposite C and the side adjacent to C.

Steps:
1. Identify the sides relative to angle C:
- Opposite = AB (the vertical side).
- Adjacent = BC (the horizontal side).
2. Compute the ratio opposite/adjacent = AB/BC.
3. Angle C = arctan(AB/BC). Use a calculator in degree mode and round to the nearest degree.

Example: if AB = 9 and BC = 12, angle C = arctan(9/12) = arctan(0.75) ≈ 36.87°, so C ≈ 37°.

Give me the numeric side lengths shown in your diagram (AB and BC, or all three sides) and I will compute the rounded angle for you.
