Question

Which trig function and ratio would you use to solve the following?

Answer 1

Answer:

$cos(30)= \frac{4}{x}$

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

$cos(30)= \frac{adjacent}{hypotenuse}$

$cos(30)= \frac{4}{x}$
