Angle ABC is taken by a dilation witch enter P and Scale factor 1/3 to angle A'B'C'. The measure of angle ABC is 21∘. What is the measure of angle A'B'C'.

Step-by-step explanation:

Given

ABC dilated to A'B'C'

Required

Determine <A'B'C'

From geometry, we understand that dilation do not affect angles.

In other words, when ABC is dilated to A'B'C, the angles of A'B'C' retains the angles in ABC.

Using the above analysis:

Hence,

(x+3)(x+7)

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.
