Question

what is the value of x? 119 101 61 140 (and a triangle with angles 79°, 40° and an exterior angle x°)

Explanation:

Step1: Find the third angle of the triangle

The sum of the interior angles of a triangle is $180^\circ$. Given two angles are $79^\circ$ and $40^\circ$, so the third interior angle is $180 - 79 - 40 = 61^\circ$.

Step2: Find the value of \( x \)

The angle \( x^\circ \) and the third interior angle are supplementary (they form a linear pair), so \( x = 180 - 61 = 119 \).

Answer:

119
