Write a proportion for the value of ?
(2 separated questions)

2

Step-by-step explanation:

Because the lenthe of one side is 8 and the lenth of the other is 16 so 16/8=2, so you could use 2 to get 6 from 3x2.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
