Answer:

√19 or 4.36

Step-by-step explanation:

Since one leg is missing, you need to use Pythagorean theorem for this.

The hypotenuse is known so,

c² - a² = b²

c = 10

a = 9

b = ?

10² - 9² = b²

100 - 81 = b²

19 = b²

b = √19

All really need to do is pick one number. so, we will go with 6 and 87.

6 times 12 is 72 then you subtract that from $87.

That would be 15

To double check, you can use another one. 9 and 123.

9 times 12 is 108. subtract that from 123 and you get 15.

Your answer is B) $15

Hope I helped :)
