Answer:
A polygon has n sides.There of its exterior angles are 70 degree, 25 degree, 15 degree while the remaining (n-3) exterior angles are each equal to 50 degree.
Step-by-step explanation:
Sum of the exterior angles is always 360.
Equatiion:
(n-3)50+70+25+15 = 360
(n-3)50+110 = 360
(n-3)= 250/50 = 5
n = 8
