What is KM + IK?

KM+IK=-10

Step-by-step explanation:

G H =

J KL M N O =

− 4 − 3 − 2 − 1 =

0= -10

1= -10

2= -10

3= -10

4=-10

K M + I K = − 10

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
