Answer:

I'm not sure what you mean by set up the equation, however X=6

Step-by-step explanation:

first you add the 7x with 21x

so you have 28x+23-11=180

second step is subtracting 11 from 23

so now you have 28x+12=180

the third step is 28x+12-12=180-12

so you have 28x=168

and the you divid both sides by 28 and you get 6

How do you this question? Please explain.

Nuetrik [128]

Answer:

Step-by-step explanation:

Recognize that all the triangles are right triangles, so are similar to each other. In these similar triangles, the ratio of the short side to the long side is the same for all.

... CB/CA = CT/CB

... CB² = CA·CT = 10·6 = 60 . . . . . . . . . . multiply by CA·CB; substitute values

... CB = √60 = 2√15 . . . . . . . take the square root; simplify

Comment on this solution

The altitude to the hypotenuse of a right triangle (CB in this case) divides the hypotenuse into lengths such that the altitude is their geometric mean. That is ...

... CB = √(AC·CT) . . . . as above

This is true for any right triangle — another fact of geometry to put in your list of geometry facts.
