Find the complementary angle of each of the following angles:
`70^(@)`

Answer

To find the complementary angle of \(70^\circ\), we can follow these steps:

### Step 1: Understand the concept of complementary angles
Complementary angles are two angles whose sum is \(90^\circ\). If we have an angle \(A\) and its complementary angle \(B\), then:
\[ A + B = 90^\circ \]

### Step 2: Set up the equation
In this case, we have:
\[ 70^\circ + \text{(complementary angle)} = 90^\circ \]

### Step 3: Isolate the complementary angle
To find the complementary angle, we can rearrange the equation:
\[ \text{(complementary angle)} = 90^\circ - 70^\circ \]

### Step 4: Perform the subtraction
Now, we calculate:
\[ \text{(complementary angle)} = 90^\circ - 70^\circ = 20^\circ \]

### Step 5: State the final answer
Thus, the complementary angle of \(70^\circ\) is:
\[ \text{Complementary angle} = 20^\circ \]
