Question

${45}^{\circ }$ can be obtained by drawing the angles of measure

• A. $10,30$
• B. $15,30$
• C. $60,90$

Answer 1

The correct option is B $15,30$

If we plot ${15}^{\circ }$ and ${30}^{\circ }$ angles then ${45}^{\circ }$ can be obtained very easily.


We know ${45}^{\circ }$ = ${15}^{\circ }$ + ${30}^{\circ }$

$\therefore {45}^{\circ }$ is obtained.
