Answer 1

Answer:

hyya

Step-by-step explanation:

sin (a+b)=1 only if sin (a+b)= 90 (eq 1)

sin (a-b)=1/2 only if sin (a-b)=30(eq 2)

by elimination methode their signs will change

sin a (and) sin a will get cancel +b +b = 2b

90-60 =30

there fore 2b=30

b =30/2

b =15

90_15= a

hpe it hlps uh

b = 15
