Look at the figure below:

quester [9]

Answer:

cos y° = b divided by 6

Step-by-step explanation:

Trigonometric ratios :

$Sin \theta = \frac{Perpendicular}{Hypotenuse}$

We are given that sin y° = a divided by 6

$sin y^{\circ}=\frac{a}{6}$

On comparing

Perpendicular = a

Hypotenuse = 6

$Tan \theta= \frac{Perpendicular}{Base}$

tan y°=a divided by b

On comparing

Perpendicular = a

Base = b

So, $cos \theta = \frac{Base}{Hypotenuse}$

$Cos y^{\circ}=\frac{b}{6}$

So, Option d is true

cos y° = b divided by 6
