To find the distance across a small lake, a surveyor has taken the measurements shown. Find the distance across the lake using this information (Assume points A and B are exactly along the shoreline, and that a = 2.72 miles and b = 3.36 miles. Round your answer to two decimal places.)

x = 12

y = 15

step-by-step explanation:

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.
