Segment ef is a mid segment of triangle abc. if bc = 12 cm, what is the measure of segment ef? a. 28 cmb. 21 cmc. 6cmd. 12 cm( explain)

The measure of length of segment EF is 6 cm

C is correct.

Step-by-step explanation:

Segment EF is a mid segment of triangle ABC.

If BC = 12 cm

Please see the attachment for diagram.

EF is mid-segment of ABC

E is mid point of AB and F is mid point of AC.

Using mid point theorem.

EF is parallel to BC

EF is half of BC

Hence, The measure of length of segment EF is 6 cm

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
