उत्तर
It is given that the triangle has its angles as 45°, 64°, and 72°.
On adding these, we get
Sum of three angles = 45° + 64° + 72°
⇒ Sum of three angles = 181°
The sum of three angles of the triangle should be equal to 180°.
Since, the sum of the given angles exceeds 180°, no such triangle exists with its angles as 45°, 64° and 72°.
