Please solve step by step on paper
Dear Student,
Solution)
8) No a triangle cannot have two obtuse triangle.
Reason - If a triangle has two obtuse angles, then the sum of all the 3 interior angles will not be equal to 180 degrees.
9) According to angle sum property, the sum of all the interior angles of a triangle = 180°.
Now, according to the question,
the angles are 45°, 64° and 72°.
So, sum of angles = 45° + 64° + 72° = 181° which is greater than 180°.
Hence, the angles does not satisfy the angle sum property of a triangle.
Therefore, no triangle can be drawn having its angles 45°, 64° and 72°.
Regards!
