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:
I think it is 192
Step-by-step explanation:
Volume of cube: 5 x 4 x 8 = 160
Area of diagonal: 160/2 = 80
Length of diagonal: 80 / 0.5 x 3 = 480
AB = 480 / 5 x 2 = 192
