IS there a drawing showing that it is a right triangle?

anonymous · Answer

use this...

hypt2-leg2=base2

plug in values... and get result..

anonymous · Answer

that is on.y if it is a right triangle

Then zaibali is right, you use the formula $hypotenuse^2-leg^2=base^2$

anonymous · Answer

the data itself repreenting triangle is right triangle.

anonymous · Answer

256^2, right?
I don't have "256^2 as an answer.

anonymous · Answer

I don't understand how you can get that given 2 sides and no angles, but okay

anonymous · Answer

Not you, @allykinss

anonymous · Answer

Actually you get $256=base^2$ so you have to take the square root of both sides, not square it

anonymous · Answer

now take sqrt on both sides...
