Question

1. find the missing side length of the right triangle. 12 ft 5 ft ? 10.9

Explanation:

Step1: Identify Pythagorean theorem

For a right triangle with legs $a, b$ and hypotenuse $c$, $c=\sqrt{a^2+b^2}$

Step2: Substitute given values

$a=5$, $b=12$, so $c=\sqrt{5^2+12^2}$

Step3: Calculate squares and sum

$5^2=25$, $12^2=144$, sum: $25+144=169$

Step4: Compute square root

$c=\sqrt{169}=13$

Answer:

13 ft
