@tkhunny im doing it now!

ffrocks3 · Answer

Want me to tell you how?

anonymous · Answer

@tkhunny i mean im in that lesson.

ffrocks3 · Answer

Using the formula
c=a2+b2
Solving forb
b=c2﹣a2=162﹣52≈15.19868

anonymous · Answer

@Ffrocks3 yes!

ffrocks3 · Answer

$$C=\sqrt{a ^{2}+b ^{2}}$$

Solving for b

$$b = \sqrt{c ^{2}-a ^{2}} = \sqrt{16^{2}-5^{2}} $$

tkhunny · Answer

@Ffrocks3   Let's get a little better at notation, please.  c^2 = a^2 + b^2 is much more clear.

Also, NEVER as if the OP want's to see how.  Always get the OP to do the work.

ffrocks3 · Answer

Yea sorry about that I didn't know I will now :)

tkhunny · Answer

Also, don't change notation in the middle of the problem. "C" and "c" are not the same thing.

ffrocks3 · Answer
