Question

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

${60}^{°}$, ${30}^{°}$, and ${70}^{°}$

Answer 1

Finding the possible angles

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

If we add the given angles ${60}^{°}$, ${30}^{°}$, and ${70}^{°}$

i.e- ${60}^{°}+{30}^{°}+{70}^{°}={160}^{°}$ which is less than ${180}^{°}$

Hence, A triangle which has angles ${60}^{°}$, ${30}^{°}$, and ${70}^{°}$are not possible.
