Answer:

  49.5 units²

Step-by-step explanation:

The applicable formula is ...

  Area = 1/2·ab·sin(C) = (1/2)·15·13·sin(30.5°) ≈ 49.48499

  ≈ 49.5 . . . square units

Answer:

Thus, the area of the triangle ABC is 49.5 square units.

Step-by-step explanation:

It is given that in a triangle ABC, the measure of the side  AC is 13 and the measure of the side BC is 15 and the measure of the angle C  is 30.5.

Thus, the area of the triangle ABC is given as:

[tex]A={\frac{1}{2}}{\times}AC{\times}BC{\times}sin(30.5)[/tex]

Substituting the given values, we have

[tex]A={\frac{1}{2}}{\times}13{\times}15{\times}(0.507)[/tex]

[tex]A={\frac{98.96}{2}}[/tex]

[tex]A=49.5 units^2[/tex]

Thus, the area of the triangle ABC is 49.5 square units.
