Answer 1

Step-by-step explanation:

(i)tan(A+B)=√3

A+B=60......(1)

tan(A-B)=1/√3

A-B=30

A=30+B......(2)

from 1

A+B=60

30+B+B=60

2B=30

B=15

from 2

A=30+15

A=45

(ii)cos(2A-B)=1/2

2A-B=60

A=60+B/2.....(1)

sin(A+2B)=√3/2

A+2B=60

(60+B/2)+2B=60

60+5B=120

5B=60

B=12

from 1

A=60+B/2

A=60+12/2

A=36
