Question

Точки М и N являются серединами сторон AB и BC треугольника ABC. сторона AB равна 114, сторона. BC равна 95, сторона AC равна 88. найти MN

Answer 1

MN -средняя линия треугольника равна половине стороныАС
MN=AC/2=88/2=44

Answer 2

Given Information:

We are given that points M and N are the midpoints of sides AB and BC of triangle ABC. The length of side AB is 114, the length of side BC is 95, and the length of side AC is 88. We need to find the length of MN.

Solution:

To find the length of MN, we can use the fact that M and N are midpoints of sides AB and BC, respectively. The length of MN is equal to half the length of the side it is parallel to.

Since M is the midpoint of AB, we can find the length of AB by multiplying the length of MN by 2. Similarly, since N is the midpoint of BC, we can find the length of BC by multiplying the length of MN by 2.

Let's calculate the length of MN using the given information.

Length of AB = 2 * MN Length of BC = 2 * MN We are given that the length of AB is 114 and the length of BC is 95. We can set up the following equations:

2 * MN = 114 2 * MN = 95

Solving these equations will give us the value of MN.

2 * MN = 114 MN = 114 / 2 MN = 57

2 * MN = 95 MN = 95 / 2 MN = 47.5

Therefore, the length of MN is 57 or 47.5, depending on which side we consider.
