In a rectangular trapezoid, the sum of the angles with a smaller base = 248 find the corners of the trapezoid
| September 5, 2021 | education
Since the trapezoid is rectangular, the angle ABC = BAD = 90.
By condition, the sum of the angles (ABC + BCD) = 248.
90 + BCD = 248.
Angle ВСD = 248 – 90 = 158.
Since the sum of the angles at the side of the trapezoid is 180, the angle ADC = 180 – BCD = 180 – 158 = 22.
Answer: The angles of the trapezoid are 90, 90, 158, 22.
