Find the reference angle given: t= -5π/3.

The reference angle is

Step-by-step explanation:

The given angle is

The reference angle is the acute angle, that a given angle  makes with the x-axis.

First let us make a sketch of the given angle. See diagram in attachment.

Let be the reference angle of  

Then, from the diagram, we need to subtract from to get to .

We can therefore write the following equation and solve for .

We group like terms to get,

We collect LCM to get,

We simplify to get,

We divide through by

to get,

The correct answer is D.
