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 =)

John and Martha are contemplating having children, but John’s brother has galactosemia (an autosomal recessive disease) and Mart
Rina8888 [55]
<h2>Answer:</h2>

Probability=\frac{1}{24}

<h2>Step-by-step explanation:</h2>

As the question states,

John's brother has Galactosemia which states that his parents were both the carriers.

Therefore, the chances for the John to have the disease is = 2/3

Now,

Martha's great-grandmother also had the disease that means her children definitely carried the disease means probability of 1.

Now, one of those children married with a person.

So,

Probability for the child to have disease will be = 1/2

Now, again the child's child (Martha) probability for having the disease is = 1/2.

Therefore,

<u>The total probability for Martha's first child to be diagnosed with Galactosemia will be,</u>

Probability=\frac{2}{3}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{4}\\Probability=\frac{1}{24}

(Here, we assumed that the child has the disease therefore, the probability was taken to be = 1/4.)

<em><u>Hence, the probability for the first child to have Galactosemia is \frac{1}{24}</u></em>
