All you do is add up all of the side lengths, and you got the perimeter.
Answer: AC= 85 BC= 68 and AB=65 The sides of the triangle are all of different lengths which means that ABC is a scalene triangle.
Step-by-step explanation: A scalene triangle only has different lengths! :)
Divide the circumference by pi, then divide that by 2, then you would have the radius, and the area is r squared multiplied by pi
596 x 25% = 149
This implies 149 persons over the age of 65 voted.
I hope this helps.
