Problem 46 of 7
Use Law of Sines to find missing angle in m=7, M=40, n=10, find N.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
use inverse sine and check ambiguity.
Hidden until you reveal it.
Use inverse sine and check ambiguity for one or two possible angles.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Set sine of missing angle over its opposite side equal to known ratio.
2. Solve with inverse sine.
3. Check for supplementary angle and triangle angle sum validity.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Only principal arcsin angle when supplement is also possible.
