Question

Hi experts, I really need help on this homework question i cant figure out. It will help alot if you used cast rule and perfect triangles if possible. I really want to understand how to solve this in the future.

Solve for x, given that 0<x< 2n . Round approximate solution(s) to the nearest hundredth of a radian (only
where necessary). Exact answers must be given when possible. You must include diagrams to prove values.

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).
