Answer 1

Step-by-step explanation:

2-√3/2+1

(4-1.73+2)/2=4.27/2=2.135

Answer 2

Step-by-step explanation:

Given:

$a)sin \: 60° + cot\: 45°-cosec\:30°$

$b)sec\:60°-cos\:30°+ tan \: 45°$

To find: Find the value of trigonometric expression.

Solution:

$a)sin \: 60° + cot\: 45°-cosec\:30°$

Put the values of trigonometry functions

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

or

$=\frac{ \sqrt{3} }{2} - 1$

$b)sec\:60°-cos\:30°+ tan \: 45°$

Put the values of trigonometry functions

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

or

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

Final answer:

$a)\bf \red{sin \: 60° + cot\: 45°-cosec\:30°=\frac{ \sqrt{3} }{2} - 1}$

$b)\bf \green{sec\:60°-cos\:30°+ tan \: 45°= 3 - \frac{ \sqrt{3} }{2}}$

Hope it helps you.
