Have you considered the Law of Sines?

3. janessia Group Title

no i havent but isnt that opposite hypotenuse?

4. janessia Group Title

@tkhunny

5. ChmE Group Title

$\frac{ a }{ \sin A }=\frac{ b }{ \sin B }=\frac{ c }{ \sin C }$where a,b,c are sides and A,B,C are the angles opposite the corresponding sides

6. ChmE Group Title

$\frac{ x }{ \sin 87 }=\frac{ 21 }{ \sin 37 }$

7. tkhunny Group Title

You don't have any right angles. "hypotenuse" doesn't mean anything for this triangle.

8. ChmE Group Title

cross multiply and solve for x using algebra

9. janessia Group Title

ohk

10. ChmE Group Title

when you don't have a right triangle think law of sines or law of cosines

11. janessia Group Title

ohk so i get rid of the 37 first right?.... by multiplying?

12. tkhunny Group Title

You calculate the values for sine and then you solve for the missing item. In this case, it is only a simple multiplication.

13. janessia Group Title

i multiply 21 and 87?

14. janessia Group Title

which is 1827

15. tkhunny Group Title

No, there is not 87 or 37. You must first calculate the sine of those angle measures.

uggh this is too much and its late thanks for all you help but i cnt concentrate when im sleepy... so i will be asking this question again tomorrow.
