Its is 9 cm. I know because the 13 cm side isn't equivalent  to the 13 cm side so if you measure it like i did you will get the answer 9cm.

Since it is a right triangle, you can use the Pythagorean theorem to solve it.
The Pythagorean theorem says that the sum of the squares of the legs of the triangle is equal to the sqauare of the hypotenuse.
ac^2 + ba^2 = cb^2
ac^2 + 5^2 = 13^2
ac^2 + 25 = 169 (simplify the squares)
ac^2 = 144 (subtract 25 from both sides)
ac = 12 (take the square root of both sides)

The correct answer is C. 12 cm.

hope this helps =)

How do you find out if 5/4 is greater or less than 7/4
castortr0y [4]

Answer: 7/4 is greater

Step-by-step explanation: If you divide 7 by 4 you get 1.75. Then you divide 5 by 4 and you get 1.25. 1.75 is greater than 1.25. Also, if they have the same denominator, whichever has a higher numerator would be greater.
