    Question

    The parallel sides of a Trapezium is 20 and 46cm

    respectively and the non-parallel sides were 10 cm and 24 cm respectively. If the non-parallel sides were extended and the meet each other at m. find the value of тИаm?
    A 75тБ░ Correct Answer Incorrect Answer
    B 60тБ░ Correct Answer Incorrect Answer
    C 90тБ░ Correct Answer Incorrect Answer
    D CanтАЩt be determined Correct Answer Incorrect Answer

    Solution

    Let ABCD be the trapezium with AB тИе CD The non-parallel lines AD and BC were extended and they meet each other at point mтАж Now construct a line CE parallel to DA. AD = CE = 10cm, AE = CD = 20cm BE = (46-20) = 26cm Now, CE=10cm, BC=24cm and BE=26cm BE┬▓ = CE┬▓ + BC┬▓ Therefore Triangle BCE is a right angled triangle with тИаBCE = 90тБ░ тИаm = тИаBCE = 90тБ░ (Corresponding Angles are equal)
