A triangle has three angles, and their measures add up to 180 degrees.
An isosceles triangle has at least 2 congruent sides, and the angles opposite the congruent sides are congruent.
This triangle has one angle of 40 deg, and two angles that measure the same; call the measure of each base angle x.
x + x + 40 = 180
2x + 40 = 180
2x = 140
x = 70
The base angles measure 70 deg.
