Question

ok

Answer 1

a^2 + b^2 = c^2
a^2 + 15^2 = 17^2

Solve from here

Answer 2

\[\sqrt{17^{2}-15^{2}}=8\]

Answer 3

Okay i need steps to solve it. I'm still confused with it.

Answer 4

a^2 + 15^2 = 17^2
a^2 + 15 (15) = 17 (17)

Simplif that for me.

Answer 5

a^2 + 225 = 289?

Answer 6

Great.
a^2 + 225 = 289
- 225 -225
----------------
a^2 = 64

The square root of 64 is?

Answer 7

When you want to find the hypotenuse you add
\[b=\sqrt{a ^{2}+c ^{2}}\]
When you want to find the sides you substract
\[a=\sqrt{b ^{2}-c ^{2}}\]
\[c =\sqrt{a ^{2}-b ^{2}}\]
