Answer:
C. √89
Step-by-step explanation:
Step 1: <u>Define/formula</u>
This is a right triangle, so the Pythagorean Theorem applies.
The Pythagorean Theorem states that the legs of a right triangle, squared, must equal the hypotenuse, squared.
The legs of a triangle are the sides that form the right angle.
The hypotenuse of a right triangle is the longest side.
Step 2: <u>Solve</u>
Here, I am solving for the hypotenuse.






Step 3: <u>Conclude</u>
Since the last step is to find the square root of 89, option 'C' is the right answer.
