I need help on this other question sry if it is hard... here is the pic.

The tangent of an angle is not which of the following? a) ratiob) proportionc) fractiond) opposite over adjacent

(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

Just tell me how to set up the equation.
