Water boils at 100 \degree \text{c}100°c100, degree, c. this is 400\%400%400, percent more than my room's temperature. what is my room's temperature?

Step-by-step explanation:

Let

x------> my room's temperature

we know that

so

The equation that represent this situation is

Solve for x

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
