Proof triangles

Mathematics

No, two sides the same is not enough.
You need more proof.

Side, angle, side. (SAS).
AD = DC
Angle ADB = Angle CDB
BD = BD

By the SAS property, the two triangles are the same.

I think this is one way to prove it...

Or, similarly...use ASA, (Angle, side, angle).

Rubys market sells smoked meats by the pound the prices for several different meals are shown in the table.
vichka [17]
Question 1: <span>how much more does 1 1/4 pounds of beef cost than 1 1/4 pounds of turkey?

$4.25/pound (beef) / 4 = $1.06 per 1/4 lb = $4.25 + $1.06 = $5.31 per 1 1/4 lb
$2.85/pound (turkey) / 4 = $0.71 per 1/4 lb = $2.85 + $0.71 = $3.56 per 1 1/4 lb

$5.31 - $3.56  = $1.75 (the beef is more expensive by this much compared to the 1 1/4 lb of turkey) 

Question 2: </span><span>question 2. brad has 10 dollars to spend at ruby's. He orders 1/2 pound of sausage and 1 1/4 pounds of chicken. How much money will he brad have after he pays for this order?

$3.25 / 2 = $1.62 per 1/2 pound of sausage 
$2.50 / 4 = $0.62 per 1/4 lb of chicken + $2.50 = $3.13 per 1 1/4 lb of chicken

$1.62 (1/2 lb sausage) + $3.13 (1 1/4 lb chicken) =$4.75
$10 (budget) - $4.75 (total expense)  = $5.25 (Brad will have this much left from his budget)</span>
