vector G is 40.3m long in a -35.0 direction. Vector H is 63.3m long in a 270 direction. find the magnitude of their vector sum. Please I really need help!

the graph on the bottom right

i dont know

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.
