How do you this question? Please explain.
Nuetrik [128]

Answer:

(C) 2√15

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

_____

<em>Comment on this solution</em>

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.

Answer:

French=60,History=120,Music=108

Step-by-step explanation:

I think this is trying to represent the degrees of a pie chart.

To find the degree of the pi chart per person you need to 72/12=6

Than to find the amount of degrees per subject multiply 6*amount of students.

Example:

6 \times amoumt \: of \: students \:taking \: music = 6 \times 18 = 108
