If sin y° = 9 divided by c and tan y° = 9 divided by d, what is the value of cos y°?

value of is

Step-by-step explanation:

Given :  

we have to find the value of  

Using trigonometric relation between  tangent , sine and cosine we have,

We are given

Substitute,  in relation above,  we have

solve for   , we have

Simplify , we get

Thus, value of is

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
