angle a + angle b + angle c = 180° (angle sum property of triangle)
110°+35°+angle c=180°
165°+ angle c = 180°
angle c = 180°-165°
angle c = 15°
This says only 8 points not 15
It is known that the perimeter of any shape is the sum of all its sides' lengths ..
So<span> the perimeter of the park would be:
p=450+500+350+500+350=2150 m = 2.15 km
Hope this Helps (:
