Question

найдите углы параллелограмм, если один из низ на 312 меньше суммы всех его углов

Answer 1

Угол который на 312 меньше суммы всех его углов равен 360-312=48. Противоположный ему тоже 48. Два других равны по 180-48=132, т к сумма углов прилежащих к одной стороне равна 180.

Answer 2

Finding the angles of a parallelogram

To find the angles of a parallelogram, we need to consider the properties of parallelograms. One important property is that opposite angles in a parallelogram are congruent. This means that if one angle is x degrees, then the opposite angle is also x degrees.

Let's denote the angles of the parallelogram as A, B, C, and D. According to the given information, one of the angles (let's say angle A) is 312 degrees less than the sum of all the other angles (B, C, and D).

We can set up the following equation to represent this relationship:

A = (B + C + D) - 312 Since opposite angles in a parallelogram are congruent, we can also say that angle B is congruent to angle D, and angle C is congruent to angle A.

Let's denote the measure of angle B (which is congruent to angle D) as x degrees. Then, angle D is also x degrees.

Similarly, let's denote the measure of angle C (which is congruent to angle A) as y degrees. Then, angle A is also y degrees.

Using these notations, we can rewrite the equation as:

y = (x + y + x) - 312 Simplifying the equation, we get:

y = 2x - 312 Now, we have two equations:

y = 2x - 312 x + y + x + y = 360 We can solve these equations simultaneously to find the values of x and y, which represent the measures of the angles in the parallelogram.

Please note that without specific values for the angles or additional information, we cannot determine the exact measures of the angles. However, we can find the relationship between the angles using the equations above.

Let's solve the equations:

From equation we can rewrite it as:

2x + 2y = 360

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

x + y = 180

Now, we have a system of equations:

y = 2x - 312 x + y = 180

We can solve this system of equations using substitution or elimination methods to find the values of x and y.
