Question

a triangle has ______ number of obtuse angle ​

Answer 1

Step-by-step explanation:

There can only be one obtuse angle in any triangle. This is because the measures of the interior angles of a triangle always must add up to 180...

Answer 2

Answer:

1

Step-by-step explanation:

A triangle can have a maximum of 1 obtuse angle. This is because the sum of the angles must be 180. With 2 obtuse angles, the sum is already 180, which doesn't allow the third angle to be made at all. Then it's not even a triangle.
