Question

the area of a right triangle is 40 inches squared angle c is 90 degrees ac is x and bc is x +2 what is x?

Answer 1

Hmm...not sure if this right or not. But here goes anyways.
Area= 40
\[Area =(1/2)(base)(height)\]I'm assuming that ac and bc are referring to the sides, right? And since angle c is the right angle, neither is the longest side of the triangle. So it becomes this:

\[40=(1/2)(x)(x+2)\]80=(x)(x+2)
\[80=x ^{2}+2x\]\[x^{2} +2x-80=0\](x-8)(x+10)=0
Therefore x= either 8 or -10. Since we are discussing lengths, the negative number cannot be applied. So x is equal to 8.

Answer 2

Thanks, i must have looked at this thing for an hour and I just wasn't seeing it for some stupid reason

Answer 3

Haha, no problem. That happens to me a lot too.
