Which angles are coterminal with −6π5 ? select each correct answer. 14π/5 −16π/5 −π/5 −11π/5

ANSWER



EXPLANATION

Coterminal angles are angles in standard position that have the same terminal side.

To find an angle in standard position that is coterminal with



We add or subtract multiples of


The first addition gives,



We add the second multiple to get,



Since this is the maximum value among the options, we end the addition here.

Let us now subtract the first multiple to get,



We end the subtraction here because this is the least value among the options.

Therefore the angles that are coterminal with

are
