Question

For the given triangle, calculate the value of $\angle C$.

• A. ${110}^{\circ }$
• B. ${100}^{\circ }$
• C. ${50}^{\circ }$
• D. ${40}^{\circ }$

Answer 1

The correct option is A ${110}^{\circ }$

The given triangle is,

The value of the exterior angle of a triangle is the sum of opposite interior angles.

$\angle BAC+\angle CBA=\angle C$

${50}^{\circ }+{60}^{\circ }=\angle C$

${110}^{\circ }=\angle C$
