The point where two straight lines join is the vertex. Hence, the triangle has three vertices. Each vertex forms an angle. … Nettet2. Set up a system of equations. You know that the angles of the triangle add up to 180, and that the angle of a line is also 180. Hence the line at the bottom is equal to. θ = 180 − ( 9 x + 12). Now you have. ( 4 x − 3) + ( 6 x + 3) + θ = 180. Solve for x, substitute back into each angle measure, and you are finished. Share. great rock church academy
