Question

Solve triangle PQR, given:, q = 38.2, and r = 39.6

Answer 1

ok

Answer 2

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

Answer 3

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

Answer 4

the angle is Q=71 degrees

Answer 5

\[\frac{ q }{ \sin(Q) }=\frac{ p }{ \sin(P) }=\frac{ r }{ \sin(R) }\]
\[\frac{ q }{ \sin(Q) }=\frac{ r }{ \sin(R) }\]
\[\frac{ 38.2 }{ \sin(71) }=\frac{ 39.6}{ \sin(R) }\]

solve for R

Answer 6

so do I cross multiply?

Answer 7

yes

Answer 8

sorry how do you cross multiply with this case?
