Use the Sin Law to find angle C
sinC/45 = sin135/92.5
C = 20.1°
How to get from equation to answer
Click For Summary
To find angle C using the Law of Sines, the equation sinC/45 = sin135/92.5 is set up. To solve for sinC, isolate it by multiplying both sides by 45, resulting in sinC = (45/92.5) * sin(135). After performing the calculation, the angle C is determined to be approximately 20.1°. The discussion also notes that this problem relates to a physics question involving acceleration and direction change. Understanding the algebra and applying arcsin is crucial for reaching the correct answer.

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:
sin(C)= \frac{45}{92.5}\left(sin(135)\right)
Can you do that calculation to find sin(C) and then find C?
