Answer:
Step-by-step explanation:
I think you mean solve for x
Set up a proportion.
The proportion should be set up as
Large Parts of ADE = Similar Parts of ABC
DE/BC = AD/AB
DE = x
BC = 6
AD = 20
AB = 10
x/6 = 20/10 Multiply by 6
x = 20*6 / 10
x = 120 / 10
x = 12

Answer: 10.1 cm approximately</h3>
=====================================================
Explanation:
The double tickmarks show that segments DE and EB are the same length.
The diagram shows that DB = 16 cm long
We'll use these facts to find DE
DE+EB = DB
DE+DE = DB
2*DE = DB
DE = DB/2
DE = 16/2
DE = 8

Now let's focus on triangle DEC. We just found the horizontal leg is 8 units long. The vertical leg is EC which is unknown for now. We'll call it x. The hypotenuse is CD = 9
Use the pythagorean theorem to find x
a^2+b^2 = c^2
8^2+x^2 = 9^2
64+x^2 = 81
x^2 = 81 - 64
x^2 = 17
x = sqrt(17)
That makes EC to be exactly sqrt(17) units long.
If you follow those same steps for triangle ADE, then you'll find the missing length is AE = 6
---------------
So,
AC = AE+EC
AC = 6 + sqrt(17)
AC = 10.1231056256177
AC = 10.1 cm approximately
