Answer:

9

Step-by-step explanation:

We can answer this problem by using the Pythagorean theorem, which goes as follows:

a² + b² = c²

a & b are the legs (sides adjacent by 90 degrees) and c is the hypotenuse ("longer" side or side across from the 90° angle)

<u>We plug stuff in like this, and then solve:</u>

Formula:  a² + b² = c²

Plug in: <em> </em>10² + b² = \sqrt{181}²

Square root and square cancel each other out: <em> </em>10² + b² = 181

Square the 10: 100 + b² = 181

Subtract 100 from both sides: b² = 81

Square root of both sides: b = \sqrt{81}

Square root of 81: b = 9

<em>Leaving us with our answer. I hope this helps, have a nice day :)</em>
