Answer:

11.2

Step-by-step explanation:

The Pythagorean theorem means that in a right triangle the hypotenuse (the longest side, opposite the right angle) squared equals the sum of the squares of the other two sides.

Therefore

15^{2} -10^2=b^2

or

225-100=b^2=125

Now, all you have to do is find the square root of 125

\sqrt[2]{125} = 11.2

Pythagorean Theorem Formula: a^2 + b^2 = c^2

We are solving for b of the triangle.

Steps to solve:

10^2 + b^2 = 15^2

~Solve for the exponents

100 + b^2 = 225

~Subtract 100 to both sides

100 - 100 + b^2 = 225 - 100

~Simplify

b^2 = 125

~Take the square root of both sides

√b^2 = √125

~Simplify

b = 11.1803398875

~Round to the nearest tenth

11.1803398875 → 11.2

Hence, the length of "b" is <u>11.2</u>

Best of Luck!
