The approximate value of \(\cos \left(59^{\circ} 30^{\prime}\right)\) is (given \(1^{\circ}=0.0175^{\mathrm{c}}, \sin 60^{\circ}=0.8660\) )
- A \(0.5076\)
- B \(0.5176\)
- C \(0.5256\)
- D \(0.5150\)
Answer & Solution
Correct Answer
(A) \(0.5076\)
Step-by-step Solution
Detailed explanation
\( 59^{\circ} 30^{\prime} = 60^{\circ} - 30^{\prime} \) \( \Delta x = 30^{\prime} = 0.5^{\circ} = 0.5 \times 0.0175^{\mathrm{c}} = 0.00875^{\mathrm{c}} \)
