Question

complementary angles
1.
2.
3.
4.
5.
6.

Explanation:

Step1: Recall the definition of complementary angles

Complementary angles add up to \(90^{\circ}\).

Step2: Calculate each angle \(x\)

1. \(x = 90^{\circ}-22^{\circ}=68^{\circ}\) (matches \(C\))
2. \(x = 90^{\circ}-54^{\circ}=36^{\circ}\) (matches \(R\))
3. \(x = 90^{\circ}-31^{\circ}=59^{\circ}\) (matches \(A\))
4. \(x = 90^{\circ}-12^{\circ}=78^{\circ}\) (matches \(V\))
5. \(x = 90^{\circ}-68^{\circ}=22^{\circ}\) (matches \(O\))
6. \(x = 90^{\circ}-75^{\circ}=15^{\circ}\) (matches \(N\))

Answer:

1. \(C\)
2. \(R\)
3. \(A\)
4. \(V\)
5. \(O\)
6. \(N\)
