Question

2tan30°/(1+tan²30°)=​

Answer 1

Answer:

want to ask that 2tan30/1-tan²30 but asked 2tan30/1+tan²30"

don't worry !! I gave you your answer

Step-by-step explanation:

2tan30/1-tan²30 = 2(1/√3)/1-(1/√3) = 2/√3/1-1/3

=2/√3×3/2

=√3

tan60

Answer 2

Answer:

Step-by-step explanation:

Tan30 = 1/root 3

2tan30= 2/root3

1+ tan ² 30 = 1+ 1/ 3 = 4/3

2tan30/ 1+ tan²30 = 2/ root3/4/3

=root3/2
