Question

Can somene answer this ​

Answer 1

Answer:

Use the pythagorean theorem.

$a^2 + b^2 = c^2$

The length of one leg, a is 11, and the length of the hypotenuse, the longest side (or c) is 17. Substitute

$11^2 + b^2 = 17^2 \\121 + b^2 = 289$

Subtract 121 from both sides to isolate B

$b^2 + 121 - 121 = 289 - 121\\b^2 = 168$

Take the square root of both sides to isolate b

$\sqrt{b^2} =\sqrt{168} \\b = 12.961$
