Hi!
An obtuse angle is one greater than 90 degrees, a right angle one that is 90, and acute less than 90.
An obtuse triangle is one with one obtuse angle, all the rest being acute. A right triangle is one with one right angle, all the rest acute. And finally, an acute triangle is one with three acute angles.
In this case, the angles measure 83 degrees, 31 degrees, and 66 degrees. All of them are acute angles, as they're all less than 90 degrees.
Therefore, the triangle is an acute triangle.
Hope this helped!

Answer:
C. (2,4), (-3,2)(2,1)(-7,2) is not a function.
Step-by-step explanation:
An option that best approximates the percent decrease in consumption of wood power in the United States from 2000 to 2010 is (B) 11%.
<h3>
What is the percentage?</h3>
- A percentage is a number or ratio expressed as a fraction of 100 in mathematics.
- The percent sign, "%," is commonly used, but the abbreviations "pct.", "pct," and sometimes "pc" is also used.
- A percentage is a number with no dimensions; it has no unit of measurement.
To find an option that best approximates the percent decrease in consumption of wood power in the United States from 2000 to 2010:
- Looking at the numerical value of wood energy source in 2000, it is 2.25, while it drops to 2.00 in 2010.
- So, the percentage decrease in the value is given by:
- (2.25 - 2.00)/2.25 × 100
- 0.25./2.25 × 100
- 100/9
- 11.11
- ≈11
Therefore, an option that best approximates the percent decrease in consumption of wood power in the United States from 2000 to 2010 is (B) 11%.
