"Graphical Method in Getting the Resultant Vector"
1. Choose a suitable scale and frame of reference for the vectors given.
2. Draw the first vector starting from the point of origin of the reference frame. Draw the second vector starting from the arrowhead of the first vector. Then, do the same procedure in the succeeding vectors.
3. Draw a vector that will connect the tail of the first vector to the head of the last vector drawn. Measure the length using the ruler and measure the angle using a protractor.

"Component Method in Getting the Resultant Vector"
1. Draw the vectors to show its component.
2.By using the trigonometric functions-sin,tan,and cos,determine the magnitude and direction of the components.
3. Find the sum of the x components.
4. Find the sum of the y components.
5. Answers from step 3 and step 4 will be the components of the resultant vector. Use these components to find the direction and magnitude of the resultant vector, using the Pythagorean theorem and trigonometric functions.
6. To check your answer, compare the result obtained from your graphical method.
