SSS = SSS

Step-by-step explanation:

if we look for the 3 aspects of the triangle that we can work with, we only see that they specifically provide us with 2. they are both sides, so we know that it has a least 2 letter S's in the answer. but, we also can see that they share a side. that means that that side is congruent too. so, it is SSS = SSS.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

wait nvm i know the correct answer now its 100%   81 square feet
