In trapezoid ABCD, angle A = 70, angle C = 30. Find the smallest of angles B and D. In the answer, indicate its degree measure.
A trapezoid is a quadrilateral in which 2 sides are parallel to each other, while the other are not parallel.
AB parallel to DC. By the property of a trapezoid, adjacent angles add up to 180 °.
Angle A = 70 °, angle D = 180 – 70 = 110 (°).
Angle C = 30 °, angle B = 180 – 30 = 150 (°).
The smallest angle is the angle D = 110 °.
