Solution: csc stands for cosecant
csc (2n+1) x 180˚
= Csc (360n +180)
= csc (180) and the csc has a period of 360˚
= 1/ sin (180)
As sin 180 = 0 so,
csc ((2n+1) x 180 degrees) is undefined as 1/0 is undefined when you calculate it in the calculator.

Answer: 4</h3>
===============================================
Work Shown:
f(x) = |x+1|
f(-5) = |-5+1| .... x is replaced with -5
f(-5) = |-4|
f(-5) = 4
U subtract 4x by 5x and then you add 3 by -21 and the answer is x=18
Don't lie about giving branliest. People will help regardless.
