PLEASE HELP I ONLY HAVE AN HOUR also I have more so if you could go answer the others that would be great ​

Answer 1

A.) 108°

Explanation:

In order to know the answer, you have to get the value of 3π/5 rad first.

The value of π (pi) is 3.14159 or 3.14.

So, 3π/5 =
`(3 x 3.14)/(5)` =
`(9.42)/(5)` = 1.884 rad

Now that you got the value of the expression, let's convert 1.884 rad to degrees.

Remember that 1 rad is equal to 57.2958 degrees.

1.884 rad x
`(57.2958 degrees)/(1 rad)` = 107.95° or 108° (lowest term)

The equivalent of 3π/5 is 108°
