Question

Найдите тупой угол параллелограмма, если его острый угол равен 11. Ответ дайте в градусах .

Answer 1

Эти углы односторонние
сумма 180 град
тупой = 180 - острый = 180 -11 = 169 град
 

Answer 2

Finding the obtuse angle of a parallelogram

To find the obtuse angle of a parallelogram, we need to know the measurement of one of the acute angles. In this case, we are given that one of the acute angles is 11 degrees. We need to determine the measurement of the obtuse angle.

Unfortunately, the search results provided do not directly provide the answer to the question. However, we can use some mathematical properties of parallelograms to find the obtuse angle.

In a parallelogram, opposite angles are congruent. This means that if one of the acute angles is 11 degrees, then the opposite acute angle is also 11 degrees. Since the sum of the angles in a parallelogram is 360 degrees, we can subtract the sum of the acute angles from 360 to find the obtuse angle.

Let's calculate it:

Sum of the acute angles = 11 degrees + 11 degrees = 22 degrees

Obtuse angle = 360 degrees - 22 degrees = 338 degrees

Therefore, the obtuse angle of the parallelogram is 338 degrees.
