estimate! think in tens. Do not do a random guess think carefully for i am a teacher!
The answer is:
first point the length of 3 cms from the intersection of two lines,on both lines
now calculate the distance of two points.
multiply the result with 20 u can get the answer.
Note:some times it may vary 0.4 degrees..
by using a protractor
You could measure it using a protractor, derive it from basic geometric properties (for example angles of a regular polygon), or calculate it using trigonometry.
Using a protractor is the simplest way of solving the measurements of angles.
Using the formula: (number of sides -2)*180 = sum of interior angles
Using a protractor helps
You can onlymeasure angles by using a protractor.

Angles are measured using a protractor
Using the formula: (number of sides -2)*180 = sum of interior angles
The 4 interior angles of any 4 sided quadrilateral add up to 360 degrees and using a protractor will prove it.
