Respuesta :

Answer:

360

Step-by-step explanation:

The inside corners of an equilater trinagle measure 60 degrees

Besides: ∠M + ∠N = 180 because supplementary angles

∠M + 60 = 180 --> ∠M = 120

Same reasoning for the pair ∠Q , ∠R and for the pair ∠X , ∠top insideangle

Hence ∠R = 120 and ∠X = 120

Therefore, the sum of the exterior angles is

∠M + ∠R + ∠X = 360
