Hi There!

We Know:

1 angle is 100 degrees

The last 2 angles have the same measure.

Find:

The measure of the last to angles.

Solution:

A total triangle has to 180 degrees.

180 - 100 = 80

80 / 2 = 40

A and C both equal 40 degrees!

Hope This Helps :)

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
