If n represents any integer then an expression representing

If n represents any integer, then an expression representing all angles coterminal with 240° is 240° + ?

Solution

Given angle 240⁰.

Need to find the coterminal angles.

coterminal angles can be obtained by adding multiples of 360⁰ to the given angle.

So, coterminal angle = 240⁰ + 360⁰n         ( n = 1,2,3,4,5,............)
