Answer:

18

Step-by-step explanation:

Average = sum / number of terms

First 4 numbers

Average = 16

Number of terms = 4

Sum / 4 = 16

= > Sum = 16 × 4

            = 64

Next 4 numbers

Average = 20

Number of terms = 4

Sum / 4 = 20

= > Sum = 20 × 4

             = 80

Total average

Total sum = 80 + 64

                = 144

Number of terms = 8

Average = 144/8

              = 72/4

              = 36/2

              = 18

Answer:

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
