1 angle C=120 angle D=180 - 120= 60 angle A and angle B are straight 90 degrees 2 angle C= 180 - 25= 155 angle A= angle B= 90 3 angle C= 40 + 90= 130 angle D= 180 - 130= 50 angle A= angle B=90

This trapezoid is rectangular, so its two angles are 90 Then a D=360-180-120=60 b D=360-180-25=155 c C=130; D=360-180-130=50

Main: The sum of the angles adjoining the side of the trapezoid is equal to 180 degrees since they are the interior unilateral angles at the parallel lines of the base of the trapezoid and the secant side 1 angleB+angleA=180 degrees. angleA=90 degrees. So angleB is equal to 90 degrees angleD+angleC=180 degrees. So angleD is 60 degrees 2 Angle A=90 degrees; angleB is 90 degrees see. 1 First line angleC is 155 degrees cm. 1 third line 3 angleA=90 degrees; angleB is equal to 90 degrees cm. first line angleC-angleA is 40 degrees by convention angleC=angleA+40=90+40=130 degrees angleD=180-angleC=50 degrees
