PLS HELP I WILL MARK BRAINLESS What is true about angle ∠APD?

It is
to angle Angle A P C.
It is
to angle Angle C P B.

It is supplementary to angle Angle A P C.

It is vertical to angle Angle C P B.

Step-by-step explanation: i just did the assignment on ed

I hope this help :)

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
