Answer:
The price of each CD before tax is $12.50.
Step-by-step explanation:
Given:
Lamar bought 3 CDs that were each the same price, including sales tax he paid a total of 40.20.
Of that total,2.70 was tax.
Now, to find the price of each CD before tax.
So, we reduce the tax from total:
Now, as given the price of each were same:
Therefore, the price of each CD before tax is $12.50.
ΔABC ≅ ΔEDC by the SAS postulate.
<h3>What is the SAS postulate's conclusion?</h3>
Postulate of Side-Angle-Side (SAS) ,The two triangles are said to be congruent if two sides and the included angle of one triangle match those of another triangle by two sides and the included angle.
According to the SAS Postulate, two triangles are congruent if their two sides and included angles are identical to those of another triangle's two sides and included angle
The midpoint of DB and AE Given is at C.
BC ≅ CD Two equal portions are produced by the midway C.
AC ≅ CE Two equal portions are produced by the midway C.
ACB and DCE Congruent vertical angles exist.
By the SAS postulat, ABC becomes EDC.

Answer:
12cos59, about 6.18
Step-by-step explanation:
cos59 = x/12
(adjacent/hypotenuse)
x = 12cos59
plugging this into a calculator gets you about 6.18
