Solution
The correct option is A 4.87 cm
Step 1:
Draw the line segment AB of the length 3.5 cm.
Step 2:
Measure the angle A with your protractor. Make a mark at 90 degrees and draw a line from A passing through the mark.
Step 3:
Cut an arc of radius 6 cm on the line passing through the point A. The point where this arc cuts the line is the point C.
Step 4:
Draw a line from C to point B to get the required triangle ABC, as shown below.
From the above construction, we see that the measure of the third side AC is 4.87 cm
