Question

find a and b if sin a-b = 1/2 and cos a+b =1/2​

Answer 1

Step-by-step explanation:

hope it helped you out..........

Answer 2

Answer:

sin a-b = 1/2

sin a-b= sin 30

= a-b = 30

cos a+b= 1/2

cos a+b= cos 60

= a+b = 60

a-b=30

a+b=60

adding the equation,

2a=90

a=90/2

a=45

substituting a= 45 in a+b=60

45+b=60

b=60-45

b=15
