Question

if sin A =3/4 then Tan A is equal to

Answer 1

Answer:

Tan A = 3/√7

Step-by-step explanation:

sin A = 3/4

Opposite = 3

Hypotenuse = 4

Adjacent =

$\sqrt{16 - 9}$

Adjacent = √7

Tan A = Opposite/ Adjacent

Tan A = 3/√7

Answer 2

Answer:

tan A = 1.12919108387 ~ 3/√7

Step-by-step explanation:

sin A = 3/4

then ,

A = arc sin (3/4)

which can be calculated in a calculator gives -

A = 0.848 which is radians = 48.59°

where, 0.848 = 106/125

A = 106 / 125

then,

which gives,

tan (106/125 ) = 1.12919108387

where,

1.12919108387 ~ 3/√7
