## Homework Statement

A velocity vector 45 below the positive x-axis has a y-component of - 29 .

What is the value of its x-component?

## Homework Equations

Vx = |V|Cos(Theta)

Vy = |v|Sin(Theta)

## The Attempt at a Solution

Theta = -45 degrees

y-component: -29 = xSin(-45) .... where x is the magnitude of the vector

x = Sin(-45) / - 29

...x = 0.2438

So |V| = 0.24~

Vx = (0.24)Cos(-45)

...=0.171

Says it's wrong, and I dont know where to go now. Am a bit embarassed asking for help with a simple problem like this :\
