Question

№1 Три точки А,В,С лежат на прямой. Известно,что АВ=4,3 см,АС=7,5 см,ВС=3,2 см. Какая их трех точек А,В,С лежат между двумя другими? №2 Сумма двух углов,которые получаются при пересечении двух прямых,равна 60°.Найдите эти углы. Желательно написать на листочке и прислать фото)

Answer 1

№1.
Точка B лежит между двумя другими.

№2.
Я не понял этот номер. Двух углом при пересечении двух прямых? Там получаются 4 угла. Если эти углы накрестлежащие, то тогда вот решение:
60 : 2 = 30°
Ответ: 30°

Answer 2

Task 1: Three points A, B, C lie on a line. Given that AB = 4.3 cm, AC = 7.5 cm, and BC = 3.2 cm, which of the three points A, B, C lie between the other two?

To determine which point lies between the other two, we can compare the lengths of the line segments AB, AC, and BC.

Let's analyze the given lengths: - AB = 4.3 cm - AC = 7.5 cm - BC = 3.2 cm

To find the point that lies between the other two, we need to identify the longest line segment. The point that is not part of the longest line segment will be the one that lies between the other two.

Comparing the lengths, we can see that AC is the longest line segment (7.5 cm), while AB (4.3 cm) and BC (3.2 cm) are shorter.

Therefore, point B lies between points A and C.

Task 2: The sum of two angles formed by the intersection of two lines is 60°. Find these angles.

To find the angles formed by the intersection of two lines, we need to know the properties of intersecting lines and their angles.

Let's denote the two intersecting lines as line 1 and line 2. The angles formed by the intersection are denoted as angle 1 and angle 2.

According to the given information, the sum of angle 1 and angle 2 is 60°.

Therefore, we can write the equation: angle 1 + angle 2 = 60°.

Unfortunately, without further information about the specific angles or the relationship between the lines, we cannot determine the exact values of angle 1 and angle 2.

If you have a specific scenario or additional information, please provide it so that we can assist you further.
