Question 285168: If a triangle has an angle A of 50 degrees, B at 65 degrees, and a= 12, what is the measures of side c and b? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! If a triangle has an angle A of 50 degrees, B at 65 degrees, and a= 12, what is the measures of side c and b?
------------------
Use the Law of Sines:
b/sin(65) = 12/sin(50)
---
b = sin(65)[12/sin(50)]
---
b = 14.197
===================
Angle C = 180-(50+65) = 75 degrees
----
c/sin(75) = 12/sin(50)
c = sin(75)
c = 15.13
==================================
