8/10
what is the purpose of applying tangents in the final sketch?
to ensure smooth transitions between lines and circles
to define the sketch fully
to add color to the sketch
to create a 3d model

Explanation:

In sketching (especially in technical or geometric sketching), tangents are used to create smooth connections between lines and circles (or other curves). Defining the sketch fully is too vague, adding color is unrelated to tangents, and creating a 3D model is not the purpose of tangents in a final sketch. So the correct option is the first one about smooth transitions.

Answer:

To ensure smooth transitions between lines and circles
