Capital of Idaho is boise this is not a math question
3+6x+3x+ 6 = 180
9x + 9 = 180
9x = 171
x = 19
<span>A. {+8) is the answer
</span>
Remark
You must use the sin law to find this.

Multiply through by 12
12 *
*12

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.
