Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. a triangle, △ abc, has angle measures of 82°, 75°, and 23° and no sides equal (congruent) in length. how would this triangle be classified? isosceles obtuse scalene acute equilateral right isosceles acute

Explanation:

1. First, analyze the side lengths: The triangle has no equal sides, so it is a scalene triangle (isosceles has at least two equal sides, equilateral has all three equal, so these are eliminated).
2. Then, analyze the angles: All angles ($82^\circ$, $75^\circ$, $23^\circ$) are less than $90^\circ$, so the triangle is acute (obtuse has one angle greater than $90^\circ$, right has one angle equal to $90^\circ$, so these are eliminated). Combining these, the triangle is scalene acute.

Answer:

B. Scalene acute
