Objective: Use trigonometry functions to find the area of triangles.

In ΔLMN, LM=10, LN=5, and m

The area of the triangle LMN is 20.3 square units

Explanation:

Given that the measurements of the sides of the triangle are , and

We need to determine the area of the triangle.

Area of the triangle:

The area of the triangle can be determined using the formula,

Substituting the values, , and , we get,

Simplifying the terms, we have,

Multiplying the values, we get,

Dividing, we get,

Rounding off to the nearest tenth, we get,

Thus, the area of the triangle LMN is 20.3 square units.
