Question

Найдите углы треугольника, если они пропорциональные числа 2 3 и 7 С рисунком и дано

Answer 1

Ответ:

30, 45 и 105

Объяснение:

рисунок тут не нужен . складываем все части 2+3+7=12 частей. делим 180 на 12 =15 - градусная мера одной части.

умножаем 15 на количество частей:

15*2=30

15*3=45

15*7=105

Answer 2

Finding the Angles of a Triangle with Proportional Numbers

To find the angles of a triangle when they are proportional to the numbers 2, 3, and 7, we can use the concept that the ratio of the measures of the angles of a triangle is equal to the ratio of the corresponding sides.

Let's denote the angles of the triangle as A, B, and C, and the corresponding sides as a, b, and c. According to the given information, the angles are proportional to the numbers 2, 3, and 7.

We can express this proportionality as: - A : B : C = 2 : 3 : 7

Now, we can use this proportionality to find the actual measures of the angles.

Calculating the Angles

To calculate the angles, we can use the following steps:

1. Find the Sum of the Proportional Numbers: - Add the proportional numbers 2, 3, and 7 to find the sum: 2 + 3 + 7 = 12.

2. Calculate the Actual Measures of the Angles: - To find the actual measures of the angles, we can use the following formula: - A = (2/12) * 180° - B = (3/12) * 180° - C = (7/12) * 180°

- Calculating the actual measures of the angles: - A = (2/12) * 180° = 30° - B = (3/12) * 180° = 45° - C = (7/12) * 180° = 105°

Therefore, the angles of the triangle are: - Angle A: 30° - Angle B: 45° - Angle C: 105°

These are the measures of the angles of the triangle when they are proportional to the numbers 2, 3, and 7.
