Ineed the answer and exactly how you got it.

This is called order of operations or pemdas. Hope this helps

Let's convert 5pi/3 into degrees first. to change radians back to degrees, multiply by 180/pi

so 5pi/3 * 180/pi would be 300

now we know we're finding the tangent of 300 degrees

plug in tan(300) in the calculator, and you get: -1.732050807568877 which roughly rounds to -1.732

hope this helps!

p.s. can i have brainliest?
