Pls help for brainliest!!! thx so much :D

(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

Need on this geometry question. explain how you did it.

What is the measure of ac? 5 units 13 units 26 units 39 units 3x- 2b 6x + 9
