Lines cd and de are tangent to circle a as shown below: lines cd and de are tangent to circle a and intersect at point d. arc ce measures 105 degrees. point b lies on circle a. if arc ce is 105°, what is the measure of ∠cde? 52.5° 62.5° 75° 255°

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

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.
