Question

I need help thank you

Answer 1

Answer:

≈ 5

Step-by-step explanation:

You can use the Pythagorean Theorem to solve this:

$a^{2} + b^{2} = c^{2}$

Now plug in the numbers into the formula:

$6^{2} + b^{2} = 8^{2}$

36 + $b^{2}$ = 64

Subtract 36 from both sides:

36 + $b^{2}$ = 64

-36        -36

_________

$b^{2}$ = 28

Square both sides:

$\sqrt{b^2} = \sqrt{28}$

b = 5.29

b ≈ 5
