Question

(05.02)How many triangles can be made if one angle is 95° and another angle is obtuse? 1 2 More than 2 None

Answer 1

D. None. Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees.

Hope this helps!!!!!!

Answer 2

None

Explanation:

We need to know what is obtuse angle

Obtuse angle is the angle that is bigger than 90 degrees and smaller than 18- degrees.

The characteristic of a triangle is that sum of the 3 angles are equal to 180°. Unfortunately, given in the question that one angle is 95° and the other is obtuse (> 90°) so the sum of them is obviously bigger than 180°. So it is impossible to form a triangle.

Hope it will find you well.
