Points d, e, and f are not in a line. to construct a circle through points d, e, and f, begin by drawing line segments and . then construct the perpendicular bisectors of and , and name the point of intersection of the perpendicular bisectors o. how do you know that point o is the center of the circle that passes through the three points?

3 false

4 d

5 3200sq,ft

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

im pretty sure it's 4 beacsue 8/2 equals 4
