Step-by-step explanation:
we know that
The Intersecting Chord Theorem, states that When two chords intersect each other inside a circle, the products of their segments are equal.
so
In this problem
substitute
Find the length of line segment MN
substitute the value of x
Ответ:
MN = 18
Step-by-step explanation:
AD and MN are two chords intersecting inside the circle at point B.
As we know from intersecting chords theorem.
AB × BD = BN × BM
So 9(x-1) = 15 (x-1)
9x + 9 = 15x - 15
15x - 9x = 15 + 9
6x = 24
x = 4
and MN = (x-1) + 15
= (x + 14)
= 4 + 14 ( By putting x = 4 )
= (18)
Therefore, MN = 18 is the answer.
