Question

Enter the number that belongs in the green box

Answer 1

Explanation:

Use the Law of Sines since this isn't a right triangle and you can't use right triangle trig. The equation will look like this:

`(sin103)/(11.89) =(sin?)/(9)`

Cross multiply to get

`sin?=(9sin103)/(11.89)` which gives us the decimal .7375383165

Take the inverse sin of this on your calculator to find the missing angle (the 2nd key and then the sin key) to be 47.52°
