BRAINLIEST +20 pts Given trapezoid ABCD with vertices A(1,2) B(7,5) C(5,7) and D(3,6)

The length of the midsegment in simplest radical form is

The equation of the line containing the midsegment is

there is no grid

step-by-step explanation:

168

step-by-step explanation:

i am pretty sure that the answer is 168

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
