40 Points : Show your work please and the correct answer. I have been struggiling.

Remember Sine of an angle is  

opposite side

hypotenuse

So let the hypotenuse be  

x

:

sin

(

47

°

)

=

opposite side

x

sin

(

47

°

)

=

12

x

To solve for  

x

, divide  

sin

(

47

°

)

by  

12

:

x

=

12

sin

(

47

°

)

x

≈

16

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.  

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
