Find by drawing the resultant of two vectors 3 unit and 4 unit inclined to each other at 30 degree, 4 degree and 90 degrees.

I can not make a drawing here. You have to draw the parallelograms with adjacent sides at the given angles to each other and the answers are the diagonals.
Yes
To find the resultant of two vectors graphically, you can use the head-to-tail method or the component method. Let's use the head-to-tail method.
Step 1: Draw a scale diagram of the first vector.
Draw a line segment representing the first vector, which has a magnitude of 3 units. Choose a suitable scale for your diagram, such as 1 cm = 1 unit. Label the starting point as "A" and the endpoint as "B".
Step 2: Draw the second vector.
From point B, draw a line segment at an angle of 30 degrees (or 4 degrees or 90 degrees, one at a time) to represent the second vector. The magnitude of the second vector is 4 units. Label the endpoint of this line segment as "C".
Step 3: Complete the triangle.
Draw a line segment from point A to point C to complete the triangle. Label this line segment as "Resultant" or "R". This line segment represents the resultant of the two vectors.
Step 4: Measure the magnitude and direction of the resultant.
Measure the length of the line segment representing the resultant using the same scale you used for the vectors. This measurement will give you the magnitude of the resultant.
To find the direction of the resultant, measure the angle between the resultant and the first vector, using a protractor. This angle will be the direction of the resultant.
Repeat steps 2-4 for the other given angles (30 degrees, 4 degrees, and 90 degrees) to find the resultants for each angle.
Note: Make sure to use a protractor to accurately measure the angles and choose a suitable scale for your diagram to represent the vectors accurately.
