Is there a triangle with angles of 60, 70, 80 degrees.

Let us take advantage of the fact that in any triangle the sum of the magnitudes of all its three sides is always 180 °.

Therefore, if the sum of the values ​​of three angles is either greater than 180 ° or less than 180 °, then a triangle with such three angles cannot exist.

In the initial data for this task, it is reported that the values ​​of these three angles are 60 °, 70 ° and 80 °, respectively.

Let’s find the sum of these values:

60 + 70 + 80 = 130 + 80 = 210 °.

Since the sum of these three angles is greater than 180 °, a triangle with such angles does not exist.

Answer: a triangle with such angles does not exist.
