- Sin7x= Sin24 * 6.4

- Relevant Equations
- SinA/A= SinB/B

So I came across a question regarding sine rule. This is to find a missing angle. The question goes as follows

Sin7x= Sin24 * 6.4

I tried two methods to solve this.

Method 1:

x= (Sin24 * 6.4)/ Sin 7

=21.35

I basically divided both sides by Sin 7

Method 2:

Sin x= (Sin 24 * 6.4)/ 7

x= Sin-1 (Ans)

x= 21.83

Note: I used my calculator "Ans" function after dividing by 7 to calculate the Sine inverse to avoid rounding errors and such.

I am confused as to which one is the right method here. Both gives very similar answers but the fact that there is a miniscule difference still makes me worried
