Question

first we must set up our equa - using the pythagorean the - a² + b² = c² 4² + b² = 13² 16 + b² = 169 b² = ? hint: subtract the value of 16 from 169

Explanation:

Step1: Isolate $b^{2}$

We have the equation $16 + b^{2}=169$. To find $b^{2}$, we need to subtract 16 from both sides of the equation.
$b^{2}=169 - 16$

Step2: Calculate the result

$b^{2}=153$

Answer:

153
