Question

Which of the following can be the possible angles of a triangle?

${90}^{°},{50}^{°},$and ${60}^{°}$

Answer 1

We know that the sum of the angles of a triangle is always ${180}^{°}$

If we add the given angles

${90}^{°},{50}^{°},$and ${60}^{°}$

i.e- ${90}^{°}+{50}^{°}+{60}^{°}={200}^{°}$ which is greater than ${180}^{°}$

So, A triangle which has angles ${90}^{°},{50}^{°},$and ${60}^{°}$ are not possible.
