Consider a rectangular trapezoid with right angle A.
Angle C = 118
In a trapezoid, the bases are parallel.
ABC = 180-DAB = 180-90 = 90-as one-sided with DAB angle at BC || AD and secant AB.
Sum of angles in a quadrilateral 360
ADC = 360-DAB-ABC-BCD = 360-90-90-118 = 62
Answer: A = 90
B = 90
C = 118
D = 62
