Answer 2

Step-by-step explanation:

$\sin \: a \: - cos a \: = \frac{ \sqrt{3} - 1 }{2} = \frac{ \sqrt{3} }{2} - \frac{1}{2}$

we know that If a value is 60 then the value of sin a and cos a is root 3 /2 and half respectively

A = 60

$sin \: a \: + cos \: a \: = sin \: 60 + cos \: 60$

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