## danadowns Solve triangle PQR, given:, q = 38.2, and r = 39.6 one year ago one year ago

1. surdawi

ok

2. surdawi

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

3. ZakaullahUET

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

the angle is Q=71 degrees

5. surdawi

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

so do I cross multiply?

7. surdawi

yes

sorry how do you cross multiply with this case?
