Answer:
third option
Step-by-step explanation:
The opposite angles of a rhombus are congruent, thus
∠ 2 = ∠ 1 = 106°
The lower triangle has 2 congruent sides and is therefore isosceles.
Thus the base angles are congruent.
The sum of the 3 angles of a triangle = 180°
∠ 3 = [tex]\frac{180-106}{2}[/tex] = [tex]\frac{74}{2}[/tex] = 37°
