Hi!
This is an equilateral triangle. Meaning all sides equal the same.
A triangle's angles add up to 180.
60+60+60=180
Angle 2=60 degrees

By applying the basic proportionality theorem to triangle ABC, the length of DB is: A. 18 cm.
In Mathematics and Euclidean Geometry, the basic proportionality theorem states that when any of the two sides of a triangle is intersected by a straight line which is parallel to the third side of the triangle, then, the two sides that are intersected would be divided proportionally and in constant ratio.
By applying the basic proportionality theorem to triangle ABC, we have the following:
AD/DB = CE/EB
24/DB = 12/9
12DB = 216
DB = 216/12
DB = 18 cm.

Answer:
Step-by-step explanation:
X= 18
24/x=12/9
That is ad/db=ce/eb
