Question

The given relation
$\sin \left(\frac{\pi }{10}\right)=\frac{\sqrt{5}-1}{2}$ is

• A. True
• B. False

Answer 1

The correct option is B False

$\sin (\frac{\pi }{10})=\sin (\frac{{180}^{\circ }}{10})=\sin {18}^{\circ }=\frac{\sqrt{5}-1}{4}\ne \frac{\sqrt{5}-1}{2}$

So the given relation is $\text{False}$
