solve it according to hsc 11th std maths textbook

To convert the angle \(\left(\frac{4}{7}\right)^c\) into degrees, minutes, and seconds, let's break down the process step by step:

### Step 1: Express the Angle in Decimal Degrees
Given that \(\left(\frac{4}{7}\right)^c\) means the fraction \(\frac{4}{7}\) of 1 degree, first compute the decimal value of \(\frac{4}{7}\):

\[
\frac{4}{7} \approx 0.57142857 \, \text{degrees}.
\]

### Step 2: Convert Decimal Degrees to Minutes
There are 60 minutes in a degree. To find the minutes, multiply the decimal part by 60:

\[
0.57142857 \times 60 = 34.285714 \, \text{minutes}.
\]

Take the integer part (34 minutes), and move to the next step to convert the decimal part into seconds.

### Step 3: Convert Decimal Minutes to Seconds
Now, take the decimal part of the minutes (0.285714) and convert it into seconds. Since there are 60 seconds in a minute, multiply by 60:

\[
0.285714 \times 60 = 17.14284 \, \text{seconds}.
\]

Thus, the seconds part is approximately 17 seconds.

### Final Result:
The angle \(\frac{4}{7}\) degrees is equivalent to:

\[
0^\circ 34' 17''
\]

This is the final answer in degrees, minutes, and seconds.
