A, B & C form the vertices of a triangle. ∠ CAB = 90°, ∠ ABC = 64° and AC = 8.6. Calculate the length of AB rounded to 3 SF.

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
