<u>Given</u>:
Given that the triangle.
Let the length of the side a be 10 cm.
Let the length of the side b be 13 cm.
Let the measure of ∠C is 105°
We need to determine the area of the triangle.
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,
Substituting a = 10, b = 13 and ∠C = 105°, we get;
Simplifying, we get;
Rounding off to 1 decimal place, we have;
Thus, the area of the triangle is 62.8 cm²
