tan 30 = x4

sin 30 = 4x

cos 30 = x4

cos 30 = 4x

Which trig function and ratio would you use to solve the followingtan 30 x4sin 30 4xcos 30 x4cos 30 4x class=

Respuesta :

Have you found the answer to this??

Answer:

[tex]cos(30)= \frac{4}{x}[/tex]

Step-by-step explanation:

WE use the given triangle to solve for x

Given triangle is right angle triangle , so we use trigonometric rations

WE know

sin = opposite side / hypotenuse

cos = adjacent side / hypotenuse

tan= opposite side / adjacent side

For angle 30 degree, the hypotenuse is x

adjacent side have side length 4

we know the hypotenuse and adjacent side so we use cos

[tex]cos(30)= \frac{adjacent}{hypotenuse}[/tex]

[tex]cos(30)= \frac{4}{x}[/tex]
