Question

Величини кутів трикутника відносяця як 3:5:7 знайдіть більший кут трикутника​

Answer 1

Ответ:

84°

Объяснение:

Сума кутів трикутника 180°. Нехай величини кутів 3х°, 5х°, 7х°, тоді

3х+5х+7х=180°

15х=180

х=12

Більший кут має 12*7=84°

Answer 2

To find the measures of the angles in the triangle, we need to determine the actual values of the angles based on the given ratio. Let's assume the measures of the angles are 3x, 5x, and 7x, where x is a common factor.

Since the sum of the angles in any triangle is always 180 degrees, we can set up the equation:

3x + 5x + 7x = 180

Now, let's solve for x:

15x = 180 x = 180 / 15 x = 12

Now that we have the value of x, we can find the measures of the angles:

The smallest angle = 3x = 3 * 12 = 36 degrees The medium angle = 5x = 5 * 12 = 60 degrees The largest angle = 7x = 7 * 12 = 84 degrees

So, the largest angle in the triangle measures 84 degrees.
