Question

Solve for b. 7 b 12 b= ✓ [?] Pythagorean Theorem: a2 + b2 = c2 Enter

Answer 1

Answer: $b=\sqrt{95}$

Step-by-step explanation:

To solve for b, we want to use the Pythagorean Theorem as given.

b and 7 are the legs, and 12 is the hypotenuse.

$7^2+b^2=12^2$      [exponent]

$49+b^2=144$     [subtract both sides by 49]

$b^2=95$               [square root both sides]

$b=\sqrt{95}$

Now we know $b=\sqrt{95}$.
