Question

AC=12см, BC=2см, CD=3см. AB-?, AD-?

Answer 1

Ответ:

AB=10 см (12-2=10)

AD=15 см (12+3=15)

Answer 2

To find the missing lengths AB and AD, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Let's consider triangle ABC first:

AC + BC > AB 12 cm + 2 cm > AB 14 cm > AB

So, AB must be less than 14 cm.

Next, let's consider triangle ACD:

AC + CD > AD 12 cm + 3 cm > AD 15 cm > AD

So, AD must be less than 15 cm.

Therefore, the possible ranges for the lengths are:

AB: 0 cm < AB < 14 cm AD: 0 cm < AD < 15 cm

Without additional information or constraints, we cannot determine the exact values of AB and AD. They can be any length within the given ranges.
