Question

2 (cos 60° + sin 30º) - (tan 60° + cot 45') + 3 sec 30°. ​

Answer 1

Answer:

3+√3 is the answer of this question

Answer 2

Answer:

Step-by-step explanation:

=2($\frac{1}{2} + \frac{1}{2}$) - [√3+1+3($\frac{2}{\sqrt{3} }$)]

=2(1) - [$\sqrt{3}$+1+$\frac{6}{\sqrt{3} }$]

=2 - [$\frac{3+\sqrt{3}+6 }{\sqrt{3} }$]

=2-[$\frac{9+\sqrt{3} }{\sqrt{3} }$]

=2-[$\frac{(3X3)+\sqrt{3} }{\sqrt{3} }$]

=2 - [$\frac{3X\sqrt{3}\sqrt{3}+\sqrt{3} }{\sqrt{3} }$]

=2 - [$3\sqrt{3}(\frac{\sqrt{3}+1 }{\sqrt{3} } )$]

=2 - [3($\sqrt{3}+1$)]

=2 - 9$\sqrt{3} - 3$

= -1-9$\sqrt{3}$
