An Acute angle is an angle is under 90 degrees, a right angle is 90 degrees, and obtuse angle is greater than 90 degrees but less than 180 degrees.... which out of these angles you would choose an Obtuse angle.
Explanation:
All of the points must be contained within a circle that will circumscribe an equilateral triangle of area 1. (We refer to this as the inscribed triangle.) Any points on the circle that do not form an equilateral triangle will form a triangle with an area less than 1. Likewise for any points within the circle.
The circle can be circumscribed by an equilateral triangle whose side length is double that of the inscribed triangle. Since the side length is double, the circumscribing triangle will have an area 2² = 4 times that of the inscribed triangle.
The inscribed triangle has an area of 1, so the circumscribing triangle must have an area of 4.
Answer:
9.
Step-by-step explanation:
When there is an absolute value, anything within the absolute value becomes positive. Things outside the absolute values stay as they are.
|-12| - |-3| = 12 - 3 = 9.

If markup is 60% of the cost, you have
... markup = 0.60×cost
... markup/0.60 = cost
... $207.20/0.60 = cost = $345.33
_____
If markup is 60% of the selling price, the other 40% is the cost. So, the cost is 40/60 = 2/3 of the markup.
... cost = (2/3)×markup = (2/3)×$207.20
... cost = $138.13
_____
Markup can be specified in terms of either selling price or cost. Those are the usual reference values; there could be others. When only the percentage is given, you don't have enough information to work the problem. You need to know what it is a percentage of. (Example problems in your text may tell you the expected interpretation.)
The answer would be 96 square feet length
6 x (4)^2 = 96
