Homework Statement



Use the Sin Law to find angle C

sinC/45 = sin135/92.5

C = 20.1°



How to get from equation to answer :confused:
 
Physics news on Phys.org
First of all, this should probably be posted in the Math forum. As for how to get the answer, you simply isolate sinC and then use arcsin.
 
Well, my guess would be to do the algebra indicated, then do the arithmetic!

Since you want to find C, you need to isolate sin(C) by multiplying both sides by 45:
[tex]sin(C)= \frac{45}{92.5}\left(sin(135)\right)[/tex]
Can you do that calculation to find sin(C) and then find C?
 
alright i got it :) thanks guys, and tal444 its part of a physics question regarding acceleration and change in direction
 
0.o i see.
