What is the domain of the relation? PLS HELP A {x|x∈R}
B {x|x∈ℝ}
C {x|x=2}
D{x|x=2}
E {y|y=2}
F {y|y=2}
G {y|y∈R}

I think it is all real numbers

Step-by-step explanation:

plz mark me as brainliest

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
