Answer:
Third quadrant
Step-by-step explanation:
Look at the attached image. All the points are in the third quadrant.
<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
