Tara has two bags of marbles. The first bag contains 6 red marbles, ​​​​​​​5 blue marbles, and ​​​​​​​4 green marbles. The second bag contains ​​​​​​​3 red marbles, ​​​​​​​2 blue marbles, and ​​​​​​​4 green marbles. Tara will randomly select ​​​​​​​1 marble from each bag. What is the probability that Tara will select a blue marble from each bag?

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)

1. supplementary angles

2. acd and bcd
