Question

How many triangles can be drawn having its angles as ${45}^0,{64}^0$ and ${72}^0?$

• A. $1$
• B. $2$
• C. More than 2
• D. None

Answer 1

The correct option is D None

The three angles given are ${45}^{\circ }$, ${64}^{\circ }$, ${72}^{\circ }$
Now, sum of angles = $45+64+72$
Sum of angles = ${181}^{\circ }$
Sum of angles of triangle cannot be more than ${180}^{\circ }$.

Hence, triangle is not possible.
