In the figure, ΔABC ~ ΔDEF. Solve for x.
Make a proportion based on the fact that they are similar. Turn the bottom triangle until the triangles match and compare the sides. The proportion should be 16/8=x/3
do cross multiplication
So the answer should be b=4?

16x 3 /8
Nana. Did you check your work?
So it's 6?
yes
Thank you so much! Can you help me with another one?
Good job. Give yourself a pat. Do you understand how I made the proportion, though?
Yes I did!
Try to make a proportion yourself after matching up the triangles. I'll tell you whether you got it right or not ;)
x-3/4 = 12/3
Huneya. Please try to help her without guessing for her :/ At any rate, huneya's attempt was wrong.
no its not @Grazes
I got 16... I think that's wrong.
so it's 19? I was close.
Huneya's proportion was correct.. to a degree. It was only right because they were special similar triangles
