Question

1 find the measure of the remote exterior angle of the triangle. 50°

Explanation:

Step1: Recall exterior - angle property

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote - interior angles. Assuming the triangle is a right - triangle and the given $50^{\circ}$ angle is one of the non - right remote interior angles. If the other non - right interior angle is $x$, and the exterior angle is $y$. In a right - triangle, if one non - right angle is $50^{\circ}$, and using the exterior angle property.
Let the exterior angle be $y$. Then $y = 90^{\circ}+50^{\circ}$.

Step2: Calculate the exterior angle

$y=140^{\circ}$

Answer:

$140^{\circ}$
