Question

In sexagesimal system of angle measurements, $1^{\circ }=$and $1^{\prime }=$

• A. ${60}^{\prime \prime }$
• B. ${216000}^{\prime \prime }$
• C. ${3600}^{\prime }$
• D. ${60}^{\prime }$

Answer 1

Answer: (A), (D)

${60}^{\prime }$

In sexagesimal system of angle measurements,
We divide $1^{\circ }$ into $60$ equal parts or in $60$ minutes
$\Rightarrow 1^{\circ }={60}^{\prime }$
Also, $1^{\prime }$ or $1$ minute is then further divided into $60$ equal parts or ${60}^{\prime \prime }$
$\Rightarrow 1^{\prime }={60}^{\prime \prime }$
$\Rightarrow 1^{\circ }={60}^{\prime }={3600}^{\prime \prime }$
