Question

Срочно нужно,помогите пж!!!! Стороны треугольника равны 5см,8см,10см.Верно ли что треугольник АВС остроугольный?

Answer 1

Ответ:

нет, не верно

в остроуголтным треугольнике сумма двух углов должна быть больше третьей что в этом треугольнике не выйдет

Answer 2

Triangle ABC and Its Side Lengths

The given triangle ABC has side lengths of 5 cm, 8 cm, and 10 cm. We need to determine whether triangle ABC is an acute triangle.

Determining if Triangle ABC is Acute

To determine if triangle ABC is an acute triangle, we need to check if the sum of the squares of the two shorter sides is greater than the square of the longest side. If this condition is satisfied, then the triangle is acute.

Let's calculate the squares of the side lengths:

- The square of the side length 5 cm is 25 cm^2. - The square of the side length 8 cm is 64 cm^2. - The square of the side length 10 cm is 100 cm^2.

Now, let's check if the sum of the squares of the two shorter sides is greater than the square of the longest side:

- The sum of the squares of the two shorter sides (25 cm^2 + 64 cm^2) is 89 cm^2. - The square of the longest side (100 cm^2) is 100 cm^2.

Since the sum of the squares of the two shorter sides (89 cm^2) is less than the square of the longest side (100 cm^2), triangle ABC is not an acute triangle.

Conclusion

Based on the given side lengths, triangle ABC is not an acute triangle.
