Dear student

a) Given ABCD is  a trapezium ,so ABCDBAD+ADC=180°   consecutive interior angles on the same side of the transversalx+20°+2x+10°=180°3x+30=180°3x=150°x=50°Also, ABC+BCD=180°   consecutive interior angles on the same side of the transversaly+92°=180°y=180°-92°=88°b) BAD+ADC=180°   consecutive interior angles on the same side of the transversal2x+3x=180°5x=180°x=36°BAD=2×36°=72°Also,  ABCD is a isosceles trapeziumAD is congruent BCDAB is congruent  to ABCAlso, ABC+BCD180°   consecutive interior angles on the same side of the transversal72°+y=180°y=108°
