Answer:

Step-by-step explanation:
Answer:
13
Step-by-step explanation:
a^2 + b^2 = c^2
5^2 + 12^2 + c^2
25 + 144 = c^2
169 = c^2
<em>Square root both sides</em>
c = 13
You have to turn the 12 into 1/12 for its reciprocal. Then you do 4/9*1/12. You cancel the 4 and make it into a 1 and make the 12 into a 3. 9*3=27. So you get D: 1/27
