Answer:
C = 83.0°
Explanation:
This triangle has three sides, with lengths of 8 units, 16 units, and 17 units. The angle formed between the sides measuring 8 units and 16 units is angle C. Angle C is opposite the side measuring 17 units.
To find the measure of angle C, we can use the Law of Cosines.

In this case:
Substitute the values of a, b, and c into the formula, and solve for C:

Therefore, the measure of angle C, rounded to the nearest tenth, is:
