Question

question a side of the triangle below has been extended to form an exterior angle of 67°. find the value of x. answer attempt 1 out of 2 x =

Explanation:

Step1: Recall exterior - angle property

The exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles.
So, $x + 50^{\circ}=67^{\circ}$.

Step2: Solve for $x$

Subtract $50^{\circ}$ from both sides of the equation: $x=67^{\circ}- 50^{\circ}$.

Answer:

$17^{\circ}$
