Find missing angles
X=???

x=145

Step-by-step explanation:

180 - 35 = 145 and they are vertical angles

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.  

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
