Answer:
The answer to your question is the letter D.
Step-by-step explanation:
In a rhombus, the diagonals are perpendicular, then, we can conclude that ∠1 measure 90°.
Also, in a rhombus, the sides are parallel, then 41° and ∠2 are alternate interior angles, so they measure the same. ∠2 = 41°.
In a triangle, the sum of the interior angles equals 180°, then,
180° = ∠1 + ∠2 + ∠3
-Substitution
180° = 90° + 41° + ∠3
∠3 = 180° - 90° - 41°
∠3 = 49°
