Question

3найдіть гострий кут рівнобедренної трапеції,якщо сума двох ії кутів дорівнює 210 градусів

Answer 1

Сумма двух тупых углов равна 210 градусов. Т.к. трапеция равнобедренная, то эти углы по 105 градусов. Тогда острый угол трапеции равен 180 -105-75 градусов

Answer 2

Finding the acute angle of an isosceles trapezoid

To find the acute angle of an isosceles trapezoid when the sum of two of its angles is 210 degrees, we can use the fact that the sum of the interior angles of a trapezoid is 360 degrees.

Let's denote the acute angle of the isosceles trapezoid as x.

The sum of the two angles is given as 210 degrees, so we can set up the equation:

x + x = 210

Simplifying the equation, we have:

2x = 210

Dividing both sides of the equation by 2, we get:

x = 105

Therefore, the acute angle of the isosceles trapezoid is 105 degrees.
