Answer 6

Answer 7

#adventuretime

Answer 8

look at triangles
BDC and ABC

2 equal angles marked for those, so the third is also equal, and those are similar triangles

matching corresponding sides is the hardest part

Answer 9

they are similar, so they are related in shape, but are scaled up or down, different sizes, related by some scale factor
you can set up proportions of corresponding sides for the two triangles, and get a couple equations with x and y

Answer 10

AB/BD are two corresponding sides marked with values, AB/BD = 17/8
that is the scale from one to the other, sides of the larger are 17/8 the distance of the smaller triangle

Answer 11

thank you i thinki get it
