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

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:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

hope this !
