No because a right triangle has 90 degrees in it but since none of them have the measurement ABC is not a right triangle

how do you post pictures

no its not

And what would AC have to be to make it a right triangle?

- anonymous

1 thing ...

- anonymous

To solve an SSS triangle:
use The Law of Cosines first to calculate one of the angles.
then use The Law of Cosines again to find another angle.
and finally use angles of a triangle add to 180° to find the last angle.

soh cah toa ...

agree to @jakashaka123

i remember it as some old hippie caught another hippie tripping on acid ...

- anonymous

Pythagorean Theorem is the lesson this derives from? I don't even know The Law of Cosines..?

- anonymous

=)

- anonymous

sin = opposite over hypotenuse
tan = opposite over adjacent
cos = adjacent over hypotenuse

- anonymous

you would use cosine =)

- anonymous

I don't use that in my Geometry class? In fact I've never even been introduced to that.

5/8.24621125124

- anonymous

you have no other angles to go off of =)

- anonymous

so therefor you have no other possible way of knowing =)

- anonymous

Except for the Pythagorean Theorem. \[a^2+b^2=c^2\]

- anonymous

yeah you wouldnt use that here =)

- anonymous

If a^2+b^2=c^2, its a right triangle.

- anonymous

you have no angles =)

- anonymous

If they are less than it's acute. Greater than it's obtuse.

- anonymous

and you wouldnt use cosine btw

- anonymous

wait yeh you would lol

- anonymous

3^2+5^2 does not equal 2 radical 17

- anonymous

So what does C have to be to make them equal?

- anonymous

@iGreen

- anonymous

you answered your own question for the 1st part of thiss question =)

- anonymous

9+25= 34

- anonymous

"What would C have to be to make it a right triangle?" Was my question.

- anonymous

So it would be radical 34?

- anonymous

yes =)

- anonymous

Thanks. c:

- anonymous

if a^2 +b^2 = C^2

- anonymous

then yeah you would need the radical other than that it would be 5.83095189485^2

- anonymous

you will eventually learn soh cah toa =)

- anonymous

you can find angle measurements with that

- anonymous

thats what i thought you were doing lol =)
