1. Encontrar la medida de los ángulos interiores del triángulo inscrito a la circunferencia, si el arco AB = 3x, el arco BC = 5x y el arco CA = 4x

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
