Ahome has a triangular backyard. the second angle of the triangle is
77 degrees°
more than the first angle. the third angle is
1717degrees°
more than
two
times the first angle. find the angles of the triangular yard.

A triangle add up to  180 degrees so  your  question is  wrong. 

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
