−6 sin C − 6 = sin C + 1

Answer 1

Hi :)

So, when you solve, you get sinC=-1 You then think "where is the sine equal to negative one?" You might think of the unit circle or the graph of the sine curve. The sine is negative one at 270 degrees or 3pi/2

Answer 2

Assuming you want to solve for C

Use techniques from Algebra 1 to isolate sin C on one side of the eqution.

Use calculator to determine C.
