Which of the following statements is true? a. a scalene triangle can have two sides of equal length. b. a scalene triangle cannot be obtuse. c. a scalene triangle can be a right triangle. d. a scalene triangle can be equiangular.

A scalene triangle can be a right triangle.

A triangle is a shape that has three sides. A scalene triangle is a triangle that none of its sides are equal.

Option A is wrong. It's an isosceles triangle that has two sides of equal length.

Option B is wrong. An scalene triangle can be obtuse. This is because one of its angles can be more than 90°.

Option C is correct. A scalene triangle can be a right triangle. This is because one of its angles can be 90°.

Option D is incorrect. A scalene triangle cannot be equiangular since it's angles are all different.

Therefore, the correct option is C.

The correct answer is C. A scalene triangle can be a right triangle.

This is because a scalene triangle is a triangle where all of the sides and angles are different from one another. This automatically tells us that options A and D are incorrect, because equiangular triangles have all 3 angles equivalent and if two sides were of equal length in the triangle, then it would not be scalene.

This leaves us with options B and C. An obtuse triangle simply has one angle with a measure greater than 90 degrees, and a right triangle is a triangle with a right angle (an angle that measures exactly 90 degrees). Scalene triangles can be both obtuse and right, as long as the side lengths and angles are not equal to one another. This makes option B incorrect, and option C the only correct option out of the four.

Your answer is option C.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
