Answer 1

Answer:

Which class question is it

Answer 2

$\frac{ { \sin}^{2} 45 + \frac{3}{4} { \csc }^{2} 30 + { \tan }^{2} 60}{ { \sin30 }^{2} + { \cos }^{2}60 + \frac{1}{2} { \sec }^{2}45 }$

$\sin(45) = \frac{1}{ \sqrt{2} }$

$\csc(30) = \frac{1}{ \sin(30) } = 2$

$\tan(60 ) = \sqrt{3}$

$\sin(30 ) = \frac{1}{2}$

$\cos(60 ) = \frac{1}{2}$

$\sec(45) = \frac{1}{ \cos(45) } = \sqrt{2}$

$so \: \frac{ \frac{1}{2} + ( \frac{3}{4} \times 4) + 3 }{ \frac{1}{4} + \frac{1}{4} + ( \frac{1}{2} \times 2) } = \frac{ \frac{13}{2} }{ \frac{3}{2} } = \frac{13}{3}$

So your answer is 13/3.
