Question

Pythagorean theorem A=8 B=? C=17

Answer 1

b=15

Explanation:

a^2+b^2=c^2

8^2+b^2=17^2

64+b^2=289

**subtract**

b^2=225

**square root 225**

b=15

Answer 2

`\text{Solve for b:}\\\\\text{Pythagorean Theorem:}\\\\a^2+b^2=c^2\\\\\text{Plug in and solve:}\\\\8^2+b^2=17^2\\\\64+b^2=17^2\\\\64+b^2=289\\\\\text{Subtract 64 from both sides}\\\\b^2=225\\\\\text{Square root both sides}\\\\√(b^2)=√(225)\\\\\boxed{b=15}`
