A triangle has one side length of 9 centimeters (cm) and another side length of 12
cm.

Which answers are possible lengths for the third side?

Select three that apply

17
22
9
21
20
3

You did not give any other clues so logically it is not possible to find the other length unless an angle is given. So if we think that the triangle is a right angle triangle then we can use the pythagorean theorem formula to calculate the other side which is:

c^2=a^2 + b^2

Now we know can say that one side 9 cm is,"a" and 12 cm is, "b" Now place the formula values accordinly to find, "c"

c^2= 9^2 + 12^2

c= square root of 225

c= 15

The exact value for the third side can be 15cm. But without any other hints it is not possible to find the other side length of the triangle.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
