## anonymous 3 years ago Solve triangle PQR, given:, q = 38.2, and r = 39.6

1. anonymous

ok

2. anonymous

do u have anything else? or is this question complete?

3. anonymous

u need a third known element too, i-e a side or an angle

4. anonymous

the angle is Q=71 degrees

5. anonymous

$\frac{ q }{ \sin(Q) }=\frac{ p }{ \sin(P) }=\frac{ r }{ \sin(R) }$ $\frac{ q }{ \sin(Q) }=\frac{ r }{ \sin(R) }$ $\frac{ 38.2 }{ \sin(71) }=\frac{ 39.6}{ \sin(R) }$ solve for R

6. anonymous

so do I cross multiply?

7. anonymous

yes

8. anonymous

sorry how do you cross multiply with this case?

9. anonymous

|dw:1354243835590:dw|
