Given the diagram below, gitta writes m1 + m2 + m3 = 180degrees. which of the following reasons allows her to write this statement? a. triangle sum theorem b. subtraction property of equality c. definition of linear pair d. exterior angles theorem

A. Triangle sum theorem.

Step-by-step explanation:

We have been given that .

We know that angle sum property of triangle states that three angles of a triangle add up-to 180 degrees.

Since the sum of angles of a triangle is 180 degrees, therefore, option A is the correct choice.

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.
