Which expression finds the length of side b of this right triangle. PLEASE HELP. I’LL GIVE BRAINIEST

The answer is b = √(c² - a²).

Step-by-step explanation:

For right angle triangle, you can apply Pythagoras Theorem where c² = a² + b² .

Answer:

Step-by-Step Explanation:

In the given right-angled triangle, the largest angle is 90°. And side c is opposite to it, hence c is the hypotenuse.

Then, a and b are the leg sides of the triangle i.e. base and perpendicular. Then, By using Pythagoras theoram:

Now shifting a² by subtracting from both sides,

We need b, square rooting both sides

That is Option B. And we are done! :D
