Step-by-step explanation:
angle C =115° (given)
therefore,
angle D+ angle C =180° (Adjacent angle of
trapezium are
supplementary.)
angle D+ 115°=180°
angle D= 180-115
= 65°.
angle C = angle A
angle D = angle B
(reason:- opposite angle of trapezium are congruent).
angle A = angle B = angle C = angle D.
hope u like it and understand it...
