Answer:

Option C

21\°

Step-by-step explanation:

we know that

The two diagonals of a rhombus are perpendicular

so

Let

O------> the center of the rhombus

m∠AOB=90\°

Remember that

The sum of the internal angles of a triangle is equal to 180\°

therefore

in the triangle AOB

m∠AOB+m∠OAB+m∠OBA=180\°

substitute the values

90\°+(2x+1)\°+(2x+5)\°=180\°

solve for x

(4x+6)\°=90\°

4x=90\°-6\°

x=21\°

Look into my attachment

in rhombus ABCD, ∠AOB = 90°

Look at ΔAOB
the sum of inner angles = 180°
∠BAO + ∠AOB + ∠ABO = 180°
2x + 1 + 90 + 2x + 5 = 180°
4x + 96 = 180
4x = 84
x = 21
