Question

.... trigonometry.........​

Answer 1

Answer:

cos45/(sec30+cosec30)

= 0.707106781/(1.15470054+2)

= 0.707106781/(3.15470054)

= 0.224141757

Answer 2

$\frac{ \cos(45) }{ \sec(30) + \csc(30) }$

$\frac{ \frac{ \: \: \: 1}{ \sqrt{2} } }{ \frac{ \sqrt{3} }{4} + \frac{2}{1} }$

$\frac{ \frac{1}{ \sqrt{2} } }{ \frac{ \sqrt{3} + 8 }{4} }$

$\frac{1}{ \sqrt{2} } \times \frac{4}{ \sqrt{3} + 8 }$

$\frac{4}{ \sqrt{6} + 8 \sqrt{2} }$

$\frac{4}{ \sqrt{6} - 8 \sqrt{2} } \times \frac{ \sqrt{6} + 8 \sqrt{2} }{ \sqrt{6} + 8 \sqrt{2} }$

$\frac{4 \sqrt{6} + 32 \sqrt{2} }{( \sqrt{6}) {}^{2} - ( 8\sqrt{2}) {}^{2} }$

$\frac{4( \sqrt{6} + 8 \sqrt{2}) }{6 - 128}$

$\frac{4( \sqrt{6} + 8 \sqrt{2}) }{ - 122}$

$\frac{2( \sqrt{6} + 8 \sqrt{2} )}{ - 61}$
