a. efb
b. ef
c. cbf
d. def
3)
what is the measure of angle ead?
4)
find the measure of arc ef.
5)
what is the measure of fce?

Circle A, EF is a minor Arc, EAD = 45 degrees, Arc EF= 150 Degrees, and FCE = 210 I guess from the looks of the Picture.

Step-by-step explanation:

1) Circle A (because A is the center)

2) A minor arc is smaller than a semicircle so EF, CBF, and DEF

3) 180 = EAD + 90 + 52

   180 = EAD + 142

    38° = EAD

4) angle EAF = 180 - 60, or 120° so arc EF should be 120° (I believe)

5) arc FCE is opposite of EF so 360 - 120 = 240°

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.  

the homeowners insurance cost for a 115,000 wood frame house is 80,500.

step-by-step explanation:

it is given that the coverage rate for wood frame house is 0.7.

the value of wood frame house is 115,000.

.

homeowners insurance cost for a 115,000 wood frame house is

therefore the homeowners insurance cost for a 115,000 wood frame house is 80,500.
