Zero triangles.. we cant draw triangle with these angles. but the given angles are 45,64.72. if we add those we get 45+64+72=181. so we cannot draw triangle.

The sum of all three angles in any triangle anouamo to 180°. If we add the given angles, i.e., 45°+64°+72°,gives us 181°. So, no triangle exists with the given angles.

not a single triangle becaues the sum of all anglesof triangle should be 180 degre

no traingle can be drawn with this measurements because the total sum of traingle =180 so its exceeds the angle

Only one distinct triangle can be formed.We can make infinite numbers of triangle by scaling up or down its length.

zero..as the sum of angles exceeds 180 degrees.

Zero triangles. because we cant draw triangle with these angles. As the given angles are 45,64,72. if we add then we get, 45+64+72=181.so we can't draw triangle.

Can a triangle have two obtuse angles? Give reason for your answer.
No, because the sum of three angles of a triangle is 180 degree & sum of any two obtuse angles is always more than 180 degree. So, it can not be possible that a triangle have two obtuse angles.
