Find the side $ b $ of a rectangle if side $a = 10$ and diagonal $d = 26$.
Answer
$b = 24$
Explanation
To find side $ b $ use Pythagorean Theorem:
$$ a^2 + b^2 = d^2 $$After substituting $ a = 10 $ and $ d = 26 $ we have:
$$ 10^2 + b^2 = 26^2 $$ $$ b^2 = 26^2 - 10^2 $$ $$ b^2 = 676 - 100 $$ $$ b^2 = 576 $$ $$ b = \sqrt{ 576 } $$$$ b = 24 $$This page was created using
