Question

help me to solve it​

Answer 1

Answer:

3√3+ 1/6

Step-by-step explanation:

tan (A+B) = √3

But we know that tan60=√3

tan(A+B) = tan 60

A+B=60 eqn (i)

tan( A-B) = 1/√3

tan30=I/√3

A-B=30 eqn (ii)

from eqn (i) & ii

A+B+A-B=60+30

2A =90

A=45

B=15

PTV

tan 45 x sin 60 t cos 45x tan 30

1*√3/2+1/√2x 1/√3

√3/2+1/6

3√3+1/6

Hence Proved
