The value of u is :

• 
  `70 \degree`

`\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}`

As we known, measure of an exterior Angle is equal to sum of two non Adjacent interior angles, that is ~

• 
  `u - 25 + u - 26 = u + 19`

• 
  `2u - 51 = u + 19`

• 
  `2u - u = 19 + 51`

• 
  `u = 70 \degree`

Answer 2

• 70

Explanation:

Exterior angle is the sum of the non-adjacent interior angles:

• u - 25 + u - 26 = u + 19
• 2u - 51 = u + 19
• 2u - u = 19 + 51
• u = 70
