Center of rhombus bisects 90°.

Sum of angles in triangle = 180°
x + x + 14 + 90 = 180
2x + 104 = 180
2 (x + 52) = 180
x = (180 ÷ 2) - 52
x = 90 - 52
x = 38°

Answer:

A. 38

Step-by-step explanation:

Diagonals of a rhombus bisect 90° at the center. Taking O to be the center :

  • 90° + x° + (x +14)° = 180° [Angle Sum Property]
  • 2x + 104 = 180
  • 2x = 76
  • x = 38
  • Option A
