## Homework Statement

find the values of a to 1 decimal place for the interval 0 <= a <= 360 for which

5sin (a+30) = 3

## The Attempt at a Solution

I know this is really easy but i've forgotten the method :(

somthing like

(a + 30) = arcsin(3/5)

a + 30 = 36.869...

but im not sure where to go from there.

Thanks
