line segment ab has endpoints a(2, 9) and b(5, 8) . a dilation, centered at the origin, is applied to ab . the image has endpoints a ′ ( 4/3 , 6) and b ′ ( 10/3 , 16/3 ) .
what is the scale factor of this dilation?
a. 2
b. 3/2
c. 3
d. 2/3

answer: t=3

answer: idk

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
