Solve for b.5bb = [?]Evaluate the square rootbefore entering youranswer.4Pythagorean Theorem: a2 + b2 = c2Enter

Answer 1

Step-by-step explanation:

Using the Pythagorean Theorem:

`5^2=b^2+4^2`

And solving for b, we have:

`\begin{gathered} 5^2-4^2=b^2 \\ \sqrt[]{5^2-4^2}=b \end{gathered}`

Solving the exponents and the square root we find b:

`\begin{gathered} b=\sqrt[]{25-16} \\ b=\sqrt[]{9} \\ b=3 \end{gathered}`

Answer:

b = 3
