Question

PLEASE HELP ME
I TRIED BUT IT DOESN'T MATCH WITH MY ANSWER​

Answer 1

Answer:

tan30°=1/√3

given, 2tan30°/1-tan²30°

2(1/√3)/1-1²/√3²

2/√3/1-1/3

2/√3/2/3

3/√3

=√3

hence proved

Answer 2

Step-by-step explanation:

This can be written as tan30+tan30/1-tan30tan30.this formula is tan(A+B)=tanA+tanB/1-tanAtanB.therefore,the answer is tan(30+30)=tan60=3^1/2
