Step-by-step explanation:

PLS GIVE BRAINLIEST

Im not here to answer. I'm just here to give a second answer so that you can brainliest the first question

Step-by-step explanation:

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

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
