Answer:
ASA
Step-by-step explanation:
∠BAC ≈ ∠CAD
AC = AC
∠BCA ≈ ∠ACD
So let's call x the amount of ounces in Solution A
So then the equation would look something like this.
0.65(x) + 0.9(130-x) = 0.7(130)
To make it easier, multiply both sides by 100:
65(x) + 90(130-x) = 70(130)
multiply.
65x + 11700 - 90x = 9100
Make sure that x is on one side and the numbers are on the other:
-25x = -2600
The negatives cancel out:
25x = 2600
Solve for x:
x = 104.
So then Solution A has 104 ounces, and Solution B has 130 - 104 ounces, which is 26 ounces.

Answer:
Step-by-step explanation:
The lengths of the sides are 7x, 9x, and 12x.
7x + 9x + 12x = 84
28x = 84
x = 3 in
Sides: 21 in, 27 in, 36 in
