You can put this solution on YOUR website! Find the angle θ. (Use either the Law of Sines or the Law of Cosines, as appropriate.) (Round your answer to one decimal place.)
a = 12, c = 6, angleC=25 degrees. find thetha in degrees
--------------------
If you assume that angle(theta) is A, the Law of Sines says:
---
sin(A)/a = sin(C)/c
--------------------
sin(A) = 12[sin(25)/6]
---
sin(A) = 2*sin(25)
sin(A) = 0.84523...
A = arcsin(0.84523...) = 57.70 degrees
