In the rectangle below ac=30 units what is de

(01.02 lc) angle abc has point e on ray ba and point d on ray bc. points e and d are equidistant from point b. to bisect angle abc, which of the following needs to be identified for the construction? the distance between points e and d the point in the angle that is equidistant from points e and d the endpoint of rays ba and bc the point outside of the angle that is equidistant from points e and d

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
