Find A, B, and C. This is the information that is given.

The answer to your question is the third option

Step-by-step explanation:

Use proportions to solve this problem

-Here we can notice 3 triangles, a large, a medium and a small sized triangle.

To find b compare the medium and the small triangle

             b/12 = 12/9

-Solve for b

             b = 12(12)/9

             b = 144/9

             b = 16

-To find c compare the large triangle and the medium sized triangle

             c /(9 + 16) = 16/c

-Solve for c

              c/ 25 = 16/c

              c² = (25)(16)

               c² = 400

               c = 20

-To find a compare the small triangle and the large triangle

              a / 9 = (9 + 16)/a

-Solve for a

              a² = 9(9 + 16)

              a² = 9(25)

              a² = 225

              a = 15

Correct  Third a = 15, b = 16, c = 20

Step-by-step explanation:

We use Pythagoras' theorem

a² = 9² + 12² = 81 + 144 = 225

a = √225 = 15

a = 15

We use Euclid's claim

b · 9 = 12² ⇒ b = 122/9 = 16

b = 16

c² = 12² + b² = 12² + 16² = 144 + 256 = 400

c = √400 = 20

c = 20
