i have a problem to solve.

3sin(4x-20)=1.2

should i solve in radians or degree mod on calculator as it gives different answers?

thanks

Generally speaking, problems that specifically deal with

**angles**and triangles, have the angles measured in degrees. But problems in which the trig functions are treated simply as "functions" of a variable, x, have x in radians.
