AABC is dilated by a factor of , to produce AA'B'C! 28
34
30
62
16
What is A'B', the length of AB after the dilation? What is the measure of ZA'?
A. A'B = 17, mZA = 140
B. A'B = 17, mL A'= 280
C. AB' = 15, mZA'= 62°
D. AB = 68, m ZA' = 280

ok then what happened.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1

step-by-step explanation:

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
