If the largest angle in a triangle is 70o, what is the least possible value of the smallest angle of the triangle?

The sum of the interior angles of a triangle is 180. The question states that the largest of the angles is 70o. We are interested in finding the least possible value of the smallest of the three angles. The least value for the smallest angle will be when the other two angles are as large as possible. The largest value that the other two angles can take is 70o each. Therefore, the least value of the smallest of the angles = 180 - 70 - 70 = 40o
