The boundary line is dashed or dotted. The answer is choice A.

Why is the boundary dashed or dotted? Because this tells the reader "do not include the boundary as part of the solution set". In other words, if a point is on the boundary line, then it is not a solution.

For instance, the point (0,2) satisfies x+y = 2 so it lays on the boundary line. However, note what happens when we plug (x,y) = (0,2) into the inequality
x+y < 2
0+2 < 2
2 < 2
The last inequality is false. The value 2 is not smaller than itself. So that's why (0,2) is not part of the solution set. This applies to every other point on the boundary line x+y = 2.

Just think of it like this:
Signs with the line under it = Solids
Signs with no line under it = Dashed

Hey There!

Lets Just Work through your answers,

ⓧ A - An isosceles triangle is a triangle with (at least) two equal sides, so this would not apply to the given triangle.

:) B - A scalene triangle is a triangle in which all three sides have different lengths so this applies to the given triangle. One side measures 10, one measures 11, and one measures 12.1

ⓧ C - A right triangle is a type of triangle that has one angle that measures 90 degrees, which this triangle does not so this does not apply.

ⓧ D - In geometry, an equilateral triangle is a triangle in which all three sides are equal, so this does not apply to the given triangle.

ⓧ E - An obtuse triangle is a triangle with one obtuse angle (greater than 90°) and two acute angles, so this does not apply to the given triangle.

:) F - An acute triangle (or acute-angled triangle) is a triangle with three acute angles less than 90 degrees. So this applies to the given triangle.

In Summary, B & F classify the given triangle correctly.

If you could rate five starts & give brainliest that would be greatly appreciated!

Hope I helped, Have a good day.
