Answer:
11.6 mi
Step-by-step explanation:
9.3^2+6.9^2 = 134.1
sqrt134.1 = approx 11.6
Step-by-step explanation:
Draw lines from one vertex to the other vertices, splitting the polygon into triangles. If the polygon has n sides, there will be n−2 triangles. Each triangle's angles add up to 180°. So the sum of all the interior angles is:
S = (n−2) 180°
The mean is 1.4
The median is 4
The mode is 3
Sum of all interior angles in a triangle = 180
let missing angle = x
x + 144 + 13 = 180
x + 157 = 180
x = 23
answer
23 degrees
