Which is the equation of an ellipse with directrices at x = ±4 and foci at (2, 0) and (−2, 0)?

X2 + y 2 = 36 x + y = 6 solve the system of equations.

`if you have a set of parallel lines a and b cut by transversal x, if angle 1 = 167 degrees, what is angle 4 and why. also what is the measure of angle 5 and why? you need to use the names of the angle relationship and explain. ''.
