Question

Find the trigonometric ratios (Hint: No Decimals).

Answer 1

Explanation:

Here we have ,

> Hypontenuse ² = 2² + 3² = 4 + 9

> Hypontenuse = √13

> Hypontenuse = 3.6 .

Therefore ,

> SinA = perp /hypotenuse = 2 / 3.6

> CosA = b/h = 3 / 3.6

> Tan A = p / b = 2 /3

> SinB = 3 / 3.6

> CosB = 2 / 3.6

> Tan B = 3 /2

Answer 2

Kindly check explanation

Explanation:

Using Pythagoras :

BA = hypotenus

BA = sqrt(2² + 3²)

BA = 3.6

SinA = opposite /hypotenus = 2 / 3.6

CosA = Adjacent / hypotenus = 3 / 3.6

Tan A = opposite / Adjacent = 2 /3

SinB = opposite /hypotenus = 3 / 3.6

CosB = Adjacent / hypotenus = 2 / 3.6

Tan B = opposite / Adjacent = 3 /2
