Consider the triangle. Which equation is true?

A. x=41
B. x=68
C. y=41
D. y= 112

x=180-68=112

So A and B are not correct.

180-112-27=41

y=41

So, C.

y = 41

Step-by-step explanation:

180 - 68 = 112= x

112+27= 139

180-139 = 41 =y

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
