Find the angles of an isosceles triangle if one of the angles is 40 degrees.

The problem has 2 cases. An isosceles triangle is one in which 2 angles at the base are equal. Consider the first case: the apex angle is 40 degrees. The angles in any triangle add up to 180 degrees. Then the sum of the two remaining angles will be equal to: 180-40 = 140. To find the value of each of them, you need to divide the amount by 2: 140/2 = 70. Thus, in the first case, the angles are: 40, 70.70 degrees. Consider the second case: one of the base angles is 40 degrees. Then the second will also be equal to 40, and the third will be 180-40-40 = 100. In the second case, we get: 40,40,100.
