Question

Chapter 10.5, Problem 53AYU

To determine

The acute angle did the receiver rotate, to the nearest tenth of a degree, where a parabolic satellite receiver is initially positioned, so its axis of symmetry is parallel to the x− axis. A motor allows the receiver to rotate and track the satellite signal. If the rotated receiver has the equation 4x2−421xy−21212x+21y2−171y+324=0
