Q-18. If 2 Sin A = 1. find the value of Tan A​

Answer 1

Step-by-step explanation:

Given ,

2 sin A = 1

=> sin A = 1/2

=> A = 30° because sin 30° = 1/2

therefore, tan A = tan 30° = 1 / (√3)

Alternative:

sin A = 1/2

we know, sin A = perpendicular / hypotenuse

perpendicular = 1

hypotenuse = 2

base = √( 2^2 - 1^2) = √3

tan A = perpendicular / base = 1 / (√3).

Answer 2

Answer:

tan A=1/√3

Step-by-step explanation:

2 SinA=1

sin A =1/2

sin 30= 1/2

A=30

now,

tanA=1/√3
