Question

Select 2 expressions that can be used to find the value of x.

14sin(55)

14cos(35)

14sin(35)

14cos(55)

Answer 1

14sin(55) and

14cos(35)

Explanation:

Greetings!!

just remember trigonometric ratios which are

`sin = (opposite)/(hypotenus) \\ cos = (adjecent)/(hypotenus) \: and \\ tan = (opposite)/(hypotenus)`

following that substitute given values to solve for x.

`sin55 = (x)/(14)`

solve for x

`x = 14 \sin(55)`

And

`\cos(35) = (x)/(14)`

solve for x

`x = \cos(35)`

Hope it helps!!!
