Side ac and side bd are perpendicular bisectors of each other. find bc and db

a. bc = 12, db = 24

b. bc = 13, db = 12

c. bc = 13, db = 24

d. bc = 12, db, 13

(C)BC = 13, DB = 24

Step-by-step explanation:

It is given that Side AC and side BD are perpendicular bisectors of each other, then from the figure, we have

DE=EB=12(Side AC and side BD are perpendicular bisectors of each other)

Now, from ΔBEC, we have

=

=

=

Therefore, BC=

Thus, BC=13

Also, DB=DE+EB

DB=12+12

DB=24

Therefore,  BC = 13, DB = 12

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.  

i think the answer is b
