Use Polya's four-step method in problem solving to solve the following problem. Five runners, Andy, Beth, Dale, Ella, and Tri, are in a one-mile race. Dale finished 5 second(s) before Tri. Tri finished 7 second (s) after beth. beth finished 7 second(s) after Ella. Ella finished 4 deco d(s) before andy. In which order did the runners finish the race?

10

step-by-step explanation:

7+3=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
