Is this a right, obtuse or acute triangle

Fourth option.

Step-by-step explanation:

Given the following question:

The given lengths do indeed form a triangle, since if you add the first two lengths of the triangle, they are greater than the third length, which means they pass the triangle inequality theorem. Which means your answer isn't the second option.

Your answer is the fourth option or "yes, it's an acute triangle." Since drawing the lines create a triangle who's all three angles are less than 90 degrees. Acute triangles angles are below 90 degrees, right angles have 90-degree angles, and obtuse angles have a greater than 90-degree angle.

Your answer is the fourth option.

Hope this helps.
