The measure of angle B is 45°.
Since the sum of the angles in a triangle is 180°, we can set up the equation as follows:
A + B + C = 180°
Given that A = 100° and C = 35°, we can substitute these values into the equation:
100 + B + 35 = 180
B + 135 = 180
B = 180 - 135
B = 45
Therefore, the measure of angle B is 45°.
