Question

Hi! So, I'm doing a test, and I've answered all my answers except for one:

Find the missing angle measure. Then classify the triangle by its measures.

Because this will not let me post a photo, I will write what all the angles are:
40 degrees (less than 90), 105 degrees (more than 90), and 35 degrees(less than 90).

A. 35; Right Triangle
(I know this isn't correct, as this triangle doesn't have any right angles.)
B. Obtuse
(One of the correct answers. I know this is true because it has one angle larger than 90 degrees, and two less than 90 degrees.)
C. Scalene
(Also true, as all sides are uneven.)
D. Acute
(Wrong. All sides are not under 90 degrees.)

I can't choose which answer would be the best. Can I, maybe, get some help? (I've explained my reasoning, please don't think I'm just looking for answers. My grades me a lot to me.)

Answer 1

I would go for scalene

Answer 2

Since the data was given as measurement of angles, I would go for properties of the triangle in terms of angles,
So I would pick <b>obtuse</b> triangle

Even though it is also a scalene triangle, "scalene" is a term associated with the lengths of the sides of a triangle.

Answer 3

By definition, B and C are both correct. We cannot say one is more correct
than the other.
