What do I have to do for this? I'm confused. :/
Luke observes the Bermuda Triangle on two maps of different sizes. The triangles are similar and have dimensions, in centimeters.

i figure that this is just a simple ratio problem (someone please correct me if im wrong). 
the two triangles only differ by a certain ratio that must be equal for all three sides. hence, one could say that the ratio of the side from Miami to Bermuda of the left triangle to the one on the right is 9:8, therefore similarly, the ratio of the side from Miami to San Juan is 3x:(x+5)

this can be rewritten as such equation:
9/8 = (3x)/(x+5)

which can be solved to:
9x+45 = 24x

hence, solving for x, we get a value of 3. 

hope this helps, cheers

Oh yeah! I forgot about ratios for a sec:)  Thanks!

the answer seems to make quite a bit of sense because when you plug in 3 into the x variable, you get 9 for the bottom side of the triangle for the left, and 8 for the right. as you can see, they are equal values of the opposing sides, which suggests its either a equilateral triangle or an isosceles triangle (judging by the picture). 

no worries!
