Question

tan30.sin60+tan260.sin30​

Answer 1

Answer:

By substituting the values of given trigonometric ratios in the above equation, we get

= 2 × (1/√3)/1 + (1/√3)2

= 2 × (1/√3)/(1 + 1/3)

= (2/√3) / (4/3)

= 6/4√3

= √3/2

Answer 2

Answer:

Your Answer is 2

Step-by-step explanation:

• we have , tan 30° = 1 / √3

                            sin 60° = √3 / 2

                            tan 60° = √3

                            sin 30°  = 1 / 2

Now , by putting these values in Que. ,

      (1 / √3 ) * (√3 / 2 ) + ( √3 )² * ( 1 / 2 )

   = ( 1 / 2 )  + ( 3 ) ( 1 / 2 )

   = ( 1 / 2 ) + ( 3 / 2 )

   = 4 / 2

   = 2 ( Ans. )
