Find the projection of the point P(42, 33, 60) onto the plane 13x + 11y + 20z = 39

Many projection
I am really tired..

You're doing something i dont know how to do but search up on google slope calculator maybe that will get you there

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
