Question

In the figure, what is the length of the tangent from the external point D to point B?

Answer 1

Says Point D to point B so answer would be 4

Explanation:

Answer 2

In the given picture, we are asked to identify and solve for the total length of the tangent line. Such as the solution is shown below:
Tangent line length = length of AB + length of BC + length of CD
Tangent line length = 3 units + 2 units + 2 units
Tangent line length = 7 units

The answer is the letter "C" which is equal to 7.
