Answer:

$IG=28.9\ ft$

Step-by-step explanation:

we know that

In the right triangle GHI

$cos(G)=\frac{IG}{GH}$ ----> by CAH )adjacent side divided by the hypotenuse)

substitute the given values

$cos(21^o)=\frac{IG}{31}$

solve for IG

$IG=cos(21^o)(31)=28.9\ ft$

see the attached figure to better understand the problem

Comment on the question

Vectors can be represented a number of different ways. Components can be given in rectangular or polar form, and the presentation can be made as a row vector, column vector, sum of orthogonal unit vectors, and other ways. We assume this is supposed to be a column vector of the form ...
