Answer:

To find the value of sin 72°3' by the using the table of natural sines we need to go through the extreme left vertical column 0° to 90° and move downwards till we reach the angle 72°3'.

Then we move horizontally to the right at the top of the column headed by 3' and read the figure 0.95372, which is the require value of sin 72°3'.

Therefore, sin 72°3' = 0.95372
