Three questions to ask.

1. How can we estimate the measure of theangle LHK in the following figure?

2. Explain the steps involved in drawing a reflex angle.(explain of 270 degree for example etc etc.)

3.Explain the steps involved in the construction of a pie chart.

1. By observation, it can be observed that the measure of ∠LHK is 90°.

2.  Reflex angle can be drawn using a protractor like any other angle.

For example, to draw reflex angle 270° we can construct an angle of measure (360° – 270°) = 90° using protractor and mark the other angle as reflex angle.

3. Here is the link to your query.
