Question

Sin thita 3/4 ho too cos thita ka maan

Answer 1

hello mate!.....
$given.... \\ sin(thita) = \frac{3}{4} \\ we \: know.... \\ sin {}^{2} x + cos {}^{2} x = 1 \\ ( \frac{3}{4} ) {}^{2} + cos {}^{2} (thita) = 1 \\ cos {}^{2} (thita) = 1 - \frac{9}{16} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{16 - 9}{16} \\ cos(thita) = \sqrt{ \frac{7}{16} } \\ cos \: thita = \frac{ \sqrt{7} }{4} \\ hope \: it \: helps \: u \: dear...$
