Question

HELP PRE-CALC!
Determine whether a triangle can be formed with the given side lengths. If so, use Heron’s formula to find the area of the triangle.

a = 240
b = 133
c = 174

Answer 1

6582.82

No triangle is formed.

11,317.51

6568.72

Answer 2

how do you know

Answer 3

well in at triangle,try to see if \[a+b>c\]
\[c+a>b\]
\[b+c>a\]

Answer 4

can you show me

Answer 5

240+133>174
240+174>133
133+174>240
check if all these is true

Answer 6

yes true

Answer 7

@Jonask

Answer 8

so now Hebrons eqaution
\[A=\sqrt{s[(s-a)(s-b)(s-c)}\]
\[s=(a+b+c)/2=(240+133+174)/2\]
have you seen it before

Answer 9

so whats the final answer?? @Jonask

Answer 10

\[\sqrt{273,5(273,5-240)(273,5-133)(273,5-174)}\]

Answer 11

so whatever the answer to that is, thats my final anwer?? @Jonask

Answer 12

Answer 17

do you have the Heron’ equation

Answer 18

I suppose that's Heron's formula which you use to calculate the area of triangle here.

Answer 19

why is it not working on wolfram

Answer 20

else you can remove root of 128085964,4375

Answer 21

square root

Answer 22

Because you typed a comma instead of of dot :S
Also, you have to put a bracket for the things under the square root

Answer 23

spazdaw ???

Answer 24
