Question

найдите углы треугрльника если известно что 2 угол больше первого на 20° а третий угол больше первого на 40°​

Answer 1

х + х - 20 + х - 40 = 180;

3х - 60 = 180;

3х = 240;

х = 80, х - 20 = 60, х - 40 = 40.

Ответ: 80, 60 и 40 градусов.

Answer 2

Ответ:

х+х-20+х-40=180

3х-60=180

3х=240

х=80

х-20=80-20=60

х-40= 80-40=40

Answer 3

Finding the Angles of a Triangle

To find the angles of a triangle when it is known that the second angle is 20° greater than the first angle and the third angle is 40° greater than the first angle, we can use the following approach:

Let's denote the first angle as x.

The second angle is then x + 20°.

The third angle is x + 40°.

To find the value of x, we can use the fact that the sum of all angles in a triangle is always 180°.

So, we have the equation: x + (x + 20°) + (x + 40°) = 180°

Solving for x will give us the value of the first angle, and then we can find the other angles accordingly.

Let's calculate the value of x.
