Answer:
- x = 50°
Step-by-step explanation:
From the given figure ,
80° is the exterior angle
x° and 30° are the two interior opposite angles to 80°
We know that
An exterior angle formed by extending the side of a triangle is equal to the sum of the two interior opposite angles
⇛ x° + 30° = 80°
⇛ x° = 80°-30°
⇛ x° = 50°
Therefore, the measure of angles x = 50°
