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?

2. Relevant 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

3. 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..
