Solution :<\/h2>\n

The value of sin 36 degrees<\/strong> is \\(\\sqrt{10 – 2\\sqrt{5}}\\over 4\\).<\/strong><\/p>\n

Proof :<\/strong><\/p>\n

We know that the value of cos 36 degrees<\/a> is \\(\\sqrt{5} + 1\\over 4\\).<\/p>\n

Putting \\(\\theta\\) = 36 in\u00a0 \\(cos \\theta\\) = \\(\\sqrt{1 – sin^2 \\theta}\\), we get<\/p>\n

cos 36 = \\(\\sqrt{1 – sin^2 36}\\) = \\(\\sqrt{1 – ({\\sqrt{5} + 1\\over 4})^2}\\) = \\(\\sqrt{10 – 2\\sqrt{5}}\\over 4\\)<\/p>\n

Hence, cos 36 degrees is \\(\\sqrt{10 – 2\\sqrt{5}}\\over 4\\).<\/p>\n","protected":false},"excerpt":{"rendered":"
