Question

if sin A = 3 by 4 calculate all trigonometric ratios​

Answer 1

Step-by-step explanation:

cos A =√7/4

tanA=3/√7

cotA=√7/3

secA=4/√7

cosecA=4/3

Answer 2

Answer:

Cos A = √7/4

Tan A = 3/√7

Cosec A = 4/3

Sec A = 4/√7

Cot A = √7/3

Step-by-step explanation:

Sin A = 3/4

BC/AC = 3x/4x

In ∆ABC

AB^2 + BC ^2 = AC^2

AB^2 + ( 3x)^2 = ( 4x )^2

AB^2 = 7x^2

AB = √7x

Cos A = AB/AC = √7/4

Tan A = BC/AB = 3/√7

Cosec A = AC/BC = 4/3

Sec A = AC/AB = 4/√7

Cot A = AB/BC = √7/3
