## anonymous 5 years ago Find the missing length using the pythagorean theorem. a= 15 b= 1/5a c= ?

1. anonymous

c^2=a^2+b^2

2. anonymous

How would you solve it?

3. anonymous

Pythagorean is straight forward; as stated above.

4. anonymous

What do you do with the "a" after 1/5?

5. anonymous

You are given value of a.

6. anonymous

So substitute 15 in for that a?

7. anonymous

Substitute 15 for the "a" to get c^2=15^2+(15/5)^2 c^2 = 225+9 = 234 take square root to find c = $\sqrt{234}$ Simplify by taking a 9 out to make it $3*\sqrt{26}$. This is your answer
