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°
