In triangle PQR:
Angle P= 49 degrees
Angle R= 37 degrees
PR=26 cm
Find QR and the area of trangle PQR.
---
QR is opposite angle P
---
Angle Q = 180-[49+37] = 94 degrees
======
QR/sin(P) = PR/sin(Q)
---------------------------
QR/sin(49) = 26/sin(94)
---
QR = (sin(49))[26/sin(94)] = 19.67 cm
=======================================
Area = (1/2)p*q*sin(R)
---
= (1/2)19.67*26*sin(37)
---
= 153.89..cm^2
=================
