Because the two triangles are similar, one is a scaled down version of the other.

You can figure out that scale by comparing two matching sides, in this case AD and AB.

AD = 2 and AB = 2+4 = 6

So 2/6 = 1/3, telling us each side of the smaller triangle is 1/3 the size of the original.

Now we need to find ED and know CB = 12. Knowing ED = 1/3 of CB:
ED = 1/3 • 12 = 4

Find the value of y.
Murrr4er [49]
I don't feel like working it out/ maybe someone will give you the answer/ but basically you would set
(3y + 1)
and add it to
(8x - 61)
to equal 180( which is the degree of a line
so it looks like this:
(3y + 1) + (8x - 61) = 180
and then solve( tell me if you need more clarification)
