Question

Find two possible lengths for CD if C, D, and E are collinear, CE = 22.1 cm, and DE = 9.5 cm.

Answer 1

Points are said to be collinear if they are on the same line. The possible lengths of CD are 31.6cm and 12.6cm

Given that:

$CE=22.1cm$

$DE = 9.5cm$

If E is between C and D, then:

$CD =CE + DE$

So, we have:

$CD =22.1cm + 9.5cm$

$CD =31.6cm$

Another possible scenario is:

If D is between C and E, then:

$CE = CD + DE$

Make CD the subject

$CD = CE - DE$

So, we have:

$CD = 22.1cm -9.5cm$

$CD = 12.6cm$

Hence, the possible values of CD are 31.6cm and 12.6cm
