In the triangle ABC shown below, DE is parallel to BC. Find the length of DB. 20

i think it's 10 because if DE is 10 so BD is the same think it's 10

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
