Solve for x. (round to the nearest tenth) This is for my high school final exam so please answer fast

Step-by-step explanation:

(sin90)/20= sin67)/x

x= 18

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.
