Trigonometric equation

[cosmic]

Hi guys,

Just wanted to check whether I have the correct answer for the following equation.

sin(theta)=19/27

Finding both solutions between 0 degrees and 360 degrees I managed to get:

(theta)= 45 degrees (to the nearest degree) and (theta)= 135 degrees (to the nearest degree).

Thanks in advance

Why were you worried? I presume that your calculator told you that 19/27= 0.703703703... and that the inverse sine of that is 44.72... degrees which rounds to 45 degrees. And 180- 45= 135 degrees.
