A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted. In Euclidean geometry any three points, when non-collinear, determine a unique triangle and a unique plane. This article is about triangles in Euclidean geometry except where otherwise noted
U could answer that question by adding 2.45+1.9=4.35
Answer:
AC = 10sin40°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = 
= 
, then
sin40° = 
( multiply both sides by 10 )
10sin40° = AC
To figure out how many cards are in each deck, divide 312 by 6. That comes out to a quotient of 52. That means there are 52 cards in each deck.
#5, the way to figure out which is the better deal, is to multiply the 2 package by the 5 package (note, DO NOT multiply the prices, only how many games they hold) that comes out to 10. So, what you do know is multiply the 2 games price by 5.
$11.98 * 5 = $59.9
Do the same with the 5 package, except multiply it by 2.
$24.95 * 2 = $49.9
Now, with these 2 answers you can tell that the 5 game package is $10 cheaper than the 2 game package, even though you are getting the same amount of games.
Hope this helps a little!
