In a rectangular trapezoid, a larger angle with a smaller base is 160 degrees. Find the degree measure of a smaller angle with a larger base.
Since the trapezoid is rectangular, a larger angle with a larger base is an acute angle ADC.
The sum of the angles of the trapezoid with its lateral side is 180, then the angle ADC = (180 – BCD) = (180 – 160) = 20.
Answer: The smaller angle for the larger base is 20.
