Answer: 18.5 in
Step-by-step explanation:
You need to be more specific
The answer is 5 units I believe
We can form two ratios to help us solve this:
(2x+6):10 = (x+6):8
(2x+6) (x+6)
--------- = --------
10 8
Cross multiply:
8(2x+6) = 10(x+6)
Foil:
16x + 48 = 10x + 60
Move like variables to the same side:
16x - 10x = 60 - 48
6x = 12
x = 2
Line AE = 2x+6
Plug 2 for x into the equation: 2(2) + 6 = 10
Hope this helps, and May the Force Be With You!

First find half of the perimeter of the triangle: s = (a + b + c) / 2 = 11.095
Then the area is:
A = Square Root [11.095 (11.095 - 7.7)(11.095 - 5.2)(11.095 - 9.29)] = 20.01999895 or 20.02 square feet rounded to 2 decimal places.
Put them all under one. so it would b 1/everything negative
