Question

sin 30 degree + tan 45 degree minus cosec, 60 degree divided / sec 30 degree + Cos 60 degree + cot 45 degree​

Answer 1

Step-by-step explanation:

$\sin(30) \ + \tan(45) - \csc(60) \div \sec(30) + \cos(60) + \cot(45)$

$\frac{1}{2} + 1 - \frac{2}{ \sqrt{3} } \div \frac{2}{ \sqrt{3} } + \frac{ \sqrt{3} }{2} + 1$

$3 + 2 \sqrt{3} - 4 \div 2 \sqrt{3} \times 2 \sqrt{3} \div 4 + 3 + 2 \sqrt{3}$

$- 1 + 2 \sqrt{3} \div 7 - + 2 \sqrt{3}$

using the law of rational or irrational

$- 2 \sqrt{3} + 12 \div 19$
