Question

PLEASE DO IT IN NOTEBOOK​

Answer 1

Answer:

solved this is the explanation

Answer 2

A= 60⁰

B = 30⁰

L.H.S.= tan(A+B)

= tan(60⁰+30⁰)

=tan90⁰

= undefined

R.S.H. =( tanA+ tanB )/(1-tanA. tanB)

= (tan60⁰+tan30⁰)/(1-tan60⁰. tan30⁰)

= {√3+ (1/√3)}/{1- √3. (1/√3)}

= (4/√3)/0

= undefined .

So, L.H.S.= R.H.S.
