Question

An angle measuring ${2100}^{\prime }$ in sexagesimal system can be written in degrees as

• A. ${45}^{\circ }$
• B. ${40}^{\circ }$
• C. ${35}^{\circ }$

Answer 1

The correct option is C ${35}^{\circ }$

Given angle in minutes ${2100}^{\prime }$
Now, we remeber $1^{\circ }={60}^{\prime }$
Or $1^{\prime }=\frac{1^{\circ }}{60}$
$\Rightarrow {2100}^{\prime }=2100\times \frac{1^{\circ }}{60}={35}^{\circ }$
