The lengths of the sides of the right triangle above are a, 3, and c. What is a in terms of c?

NemiM [27]

The expression for a in terms of c is $a^{2}= \sqrt{c^{2} -9}$ . The correct option is the third option $a^{2}= \sqrt{c^{2} -9}$

<h3>Pythagorean theorem </h3>

From the question, we are to determine the expression for a in terms of c

In the given right triangle, we can write that

$c^{2} = a^{2} +3^{2}$ (<em>Pythagorean theorem</em>)

Thus,

$c^{2} = a^{2} +9$

$a^{2}= c^{2} -9$

$a^{2}= \sqrt{c^{2} -9}$

Hence, the expression for a in terms of c is $a^{2}= \sqrt{c^{2} -9}$ . The correct option is the third option $a^{2}= \sqrt{c^{2} -9}$
