Answer 2

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

Answer 3

how do you post pictures

Answer 4

no its not

Answer 5

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

Answer 6

1 thing ...

Answer 7

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.

Answer 8

soh cah toa ...

Answer 9

agree to @jakashaka123

Answer 10

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

Answer 11

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

Answer 12

=)

Answer 13

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

Answer 14

you would use cosine =)

Answer 15

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

Answer 16

5/8.24621125124

Answer 17

you have no other angles to go off of =)

Answer 18

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

Answer 19

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

Answer 20

yeah you wouldnt use that here =)

Answer 21

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

Answer 22

you have no angles =)

Answer 23

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

Answer 24

and you wouldnt use cosine btw

Answer 25

wait yeh you would lol

Answer 26

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

Answer 27

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

Answer 28

@iGreen

Answer 29

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

Answer 30

9+25= 34

Answer 31

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

Answer 32

So it would be radical 34?

Answer 33

yes =)

Answer 34

Thanks. c:

Answer 35

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

Answer 36

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

Answer 37

you will eventually learn soh cah toa =)

Answer 38

you can find angle measurements with that

Answer 39

thats what i thought you were doing lol =)
