2. Timtime Group Title

herons formula?

3. CliffSedge Group Title

What is 's' ?

4. CliffSedge Group Title

If this is a Heron's formula situation, I'm guessing it means 'semi-perimeter.' . . .

5. Decart Group Title

if you use herons formula you get the area and then you can solve for the height then solve for an angle and your all set

6. CliffSedge Group Title

@Decart what information are you using to determine that an angle needs to be found?

7. Decart Group Title

there is nothing else to solve area angles

8. CliffSedge Group Title

The question is asking for 's' - until we know what the variable s represents, we shouldn't be making assumptions. Yes, we could completely solve the triangle if we wanted to, but I'd rather answer the actual question.

9. CliffSedge Group Title

@Timtime can you clarify what the problem is asking for? Is it referring to semi-perimeter?

10. Decart Group Title

$s=\frac{ a+b+c }{ 2 }$

11. Timtime Group Title

i got 14m^2

12. CliffSedge Group Title

So 's' means area?

13. Timtime Group Title

yea i got the answer right

14. Timtime Group Title

thank you
