Step-by-step explanation:
Given that you have the length of one side (KL) and the measure of an included angle (M), you can use the Law of Cosines to solve for (x). The Law of Cosines states:
[c^2 = a^2 + b^2 - 2ab \cos]
where (a) and (b) are the sides of the triangle, (C) is the included angle, and (c) is the side opposite angle (C). In this case, (a = 80), (b = x), and (C = 66) degrees. So, you can solve for (x) (side LM) using the following equation:
[x^2 = 80^2 + x^2 - 2 \cdot 80 \cdot x \cdot \cos(66)]
Man i dont even know, this is just an ai.
