You are getting the right one!
All the solutions to sin(x) is 0°,180°,360° as you've chosen
You can refer to the graph for reference^
hope it helps!
If you want to know the number that is equivalent to 0.05, you can calculate this using the following two steps:
0.05 equals to 5/100 <span>which simplifies to </span>1/20.
<span>
The result is 1/20.
</span>
It is impossible if you don't have any tools. You can construct angle 150 by adding together 90 and 60, both of which can be constructed without any special tools (you would need a compass and a ruler).
To construct angle 150.5 you would need a protractor. A protractor is a device that allows you to construct angles and measure them.
4m - 17 < 6m + 25 (subtract 4m from each side)
-17 < 6m - 4m + 25
-17 < 2m + 25 (subtract 25 from each side)
-17 - 25 < 2m
-42 < 2m (divide 2 from each side)
-42/2 < m
-21 < m
The answer is <u>m > -21</u>
