Remark
You must use the sin law to find this.
[tex] \dfrac{Sin(75)}{22} = \dfrac{Sin(x)}{12} [/tex]
Multiply through by 12
12 * [tex] \dfrac{Sin(75)}{22} = \dfrac{Sin(x)}{12} [/tex] *12
[tex] \dfrac{12*sin(75)}{22} = \text{sin(x)} [/tex]
0.5269 = sin(x)
Now you have to use the inverse of the sine function.
Use your calculator for that
2nd F
sin-1
(0.5269)
= 31.79 degrees. <<<<<< Answer.
There sometimes is a second answer. I don't think there is in this case.
