The spinner of the compass is two congruent isosceles triangles connected by their bases as shown in the diagram. the base of each of these triangles is 2 centimeters and the legs are 5 centimeters.
if the metal used to construct the spinner costs $13.25 per square centimeter, how much will it cost to make this part of the compass? round to the nearest cent.
cost =

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )

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
