Answer:
A. 12.21
Explanation:
Define and explain:
This a right triangle, so the Pythagorean Theorem applies. The Pythagorean Theorem states that the sum of the squared legs is equal to the squared hypotenuse.
The legs of a triangle are the sides that form the right angle.
The hypotenuse is the longest side.
Formula:
Here, I am solving for the hypotenuse.
The last step is to find the square root of 149.
The square root of 149 is irrational, of course, so I must round the square root to the nearest hundredth.
≈
Conclude:
I, therefore, believe the length of the hypotenuse is 12.21.
