The answer is x=4,5 because you are subtracting
(n - 2)180 = sum of angles (six sides)
(6 - 2)180 = y
(4) 180 = y
720= y
115+110+x+25+x-30+x+x = 720
4x + 220 = 720
4x = 720 - 220
4x = 500
x = 500/4
x = 125
A right triangle with congruent legs is always a 45-45-90 triangle. It’s true.
You just divide 384 by how many side there are
The total cost of the item with sales tax will be $ 381.6.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
An item cost $360 before tax and the sale tax is 21.60.
Then the total cost of the item with sales tax will be
Total cost = 360 + 21.6
Total cost = $ 381.6
