Question

Find the missing length using the pythagorean theorem.

a= 15
b= 1/5a
c= ?

Answer 1

c^2=a^2+b^2

Answer 2

How would you solve it?

Answer 3

Pythagorean is straight forward; as stated above.

Answer 4

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

Answer 5

You are given value of a.

Answer 6

So substitute 15 in for that a?

Answer 7

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
