Answer:
The value of x is 120°.
Explanation:
The two interior opposite angles are of 50° and 70° positively. According to the exterior angle property of a triangle, the sum of these two angles will be equal to angle x.
So, 50° + 70° = x
Hence, the value of x is 120°.
The exterior angle property of a triangle : the exterior angle of a triangle is equal to the sum of the two interior opposite angles of the triangle.
