## anonymous 5 years ago i need help finding x

1. anonymous

the formula to find it is 1st piece/alt = alt/2nd piece

2. anonymous

no idea what yu are talking about

3. anonymous

I'm not sure I understand what you mean there.

4. anonymous

im posting the picture of it now, the 1st piece would be 5/2 the alt is x and the 2nd piece is 10

5. anonymous

(5/2) / x = x /10 25 = x^2 x = 5

6. anonymous

but 5/2 is a fraction, how would it = 25?

7. anonymous

$\frac{\frac{5}{2}}{x} = \frac{x}{10} \implies 10x *\frac{\frac{5}{2}}{x} = 10x * \frac{x}{10}$

8. anonymous

Can you follow it from there?

9. anonymous

10. anonymous

oh. that's not really what we were talking about before.

11. anonymous

Ok, so the first thing to figure out is what is the length of the left and right slopes in terms of x?

12. anonymous

ya it would end up as x^2 = ( 5/2 times 10)

13. anonymous

$\frac{5}{2} \times 10 = \frac{5*10}{2} = \frac{50}{2} = 25$

14. anonymous

thanks

15. anonymous

the final answer is x = 25

16. anonymous

i mean x = 5

17. anonymous

yes
