Answer:
≈ 5
Step-by-step explanation:
You can use the Pythagorean Theorem to solve this:
[tex]a^{2} + b^{2} = c^{2}[/tex]
Now plug in the numbers into the formula:
[tex]6^{2} + b^{2} = 8^{2}[/tex]
36 + [tex]b^{2}[/tex] = 64
Subtract 36 from both sides:
36 + [tex]b^{2}[/tex] = 64
-36 -36
_________
[tex]b^{2}[/tex] = 28
Square both sides:
[tex]\sqrt{b^2} = \sqrt{28}[/tex]
b = 5.29
b ≈ 5
