One of the angles of an isosceles triangle is 105 °, and this angle is at the apex of the triangle, because its base cannot have two identical obtuse angles. The sum of the angles in any triangle is 180 °, so the sum of the angles at the base is 180 ° – 105 ° = 75 °. Each of the same angles at the base of an isosceles triangle will be equal to:
75/2 = 37.5 °.
