Your answer​

Answer 1

Step-by-step explanation:

.........................

Answer 2

Step-by-step explanation:

$sin(a + b) = \frac{ \sqrt{3} }{2}$

$sin(a - b) = \frac{1}{2}$

$a + b = 60 \: \: \: (eqution \: 1)$

$a - b = 30 \: \: \: (eqution \: 2)$

$adding \: 1 \: and \: 2$

$a = 45$

$b = 15$

$hence \: proved$
