## Homework Statement

Suppose that x=7pi/23 is a solution of the equation sinx= A where A is some constant.

Then A must be equal to [blank], and the other solution of the equation in the interval [0,2pi] must be x = [blank].

## The Attempt at a Solution

So I've plugged the value in to my calculator and found A, but I completely forget Trigonometry. How would I go about finding the second solution?

Thanks
