On the CD segment, point O was indicated. Find the length of the CD segment if CO = 16

On the CD segment, point O was indicated. Find the length of the CD segment if CO = 16, and the OD segment is 9 cm shorter than the CO segment.

1) Calculate the length of the segment OD if CO = 16 cm, and OD is 9 cm shorter than CO:

OD = CO – 9;

OD = 16 – 9;

OD = 7 cm.

2) Calculate the length of the segment CD. The segment CD is equal to the sum of the lengths of the segments CO and OD, CO = 16 cm, OD = 7 cm:

CD = CO + OD;

CD = 16 + 7;

СD = 23 cm.

Answer: the length of the CD segment is 23 cm.
