Question

Chords AB and CD intersect at point M. According to the diagram, which pair of numbers could represent lengths of segments CM
and DM?

2 and 7
2 and 10
2.5 and 6.5
3 and 6

Answer 1

Answer:

Answer:

Step-by-step explanation:

Since the product of the intersecting chords should be equal

==> AM x BM = CM x DM

==> 4 x 5 = CM x DM

==> 20 = CM x DM

Therefore CM x DM = 2 X 10

Step-by-step explanation:

Answer 2

Answer:

2 and 10

Step-by-step explanation:

Since 4*5 = 20, the other pair could be 2 and 10.
