## Homework Statement

In the figure below shows the path taken by a drunk skunk over a level ground, from initial point i to final point f. The angles are θ

_{1}= 30, θ

_{2}= 50, and θ

_{3}= 80, and the distance are d

_{1}= 5.00 m, d

_{2}= 8.00 m, and d

_{3}= 12.0 m. What are the (a) magnitude and (b) angle of the skunk’s displacement from i to f?

## Homework Equations

Using basic trigonometric functions, soh cah toa

Let X and Y stands for the summation of x and y.

Resultant vector = (X

^{2}+ Y

^{2})

^{1/2}

Let * stands for the resultant vector angle, then * = tan

^{-1}= Y / X

## The Attempt at a Solution

I have obtained the x and y component for d

_{1}. Finding x = (5.00 m)cos30 = 4.33 m and for y, (5.00m)(sin30) = 2.5 m. However, I'm having the difficulty to find the other x and y components of d

_{2}and d

_{3}because they aren't parallel to x and y axis respectively.

For example, d

_{2}is diagonal and I can't simply do (8.00 m)(cos 50) to find the x component because d

_{2}is not parallel to x axis. Hence, connecting d

_{1}and d

_{2}will not form a right triangle which is necessary to find the x and y components using soh cah toa..

Please give me an idea how to solve this..

Thank you..
