Explanation:
apply angle sum property of triangle in the given traingle ( instead of this u can write sum of all the interior angles of triangle is 180°)
so,
→ 80° + 50° + x = 180°
→ 130° + x = 180°
→ x = 180° - 130°
→ x = 50°
therefore, value of x is 50°.
hope this answer helps you dear....take care and may u have a great day ahead!.
