State whether the triangle is possible to construct if (a) In ΔABC, m∠A = 80°, m∠B = 60°, AB = 5.5 cm (b) In ΔPQR, PQ = 5 cm, QR = 3 cm, PR = 8.8 cm with diagram​

  1. Step-by-step explanation:

    Solution:

    (a) m∠A = 80°, m∠B = 60°

    m∠A + m∠B = 80° + 60° = 140° < 180°

    So, ΔABC can be possible to construct.

    (b) PQ = 5 cm, QR = 3 cm, PR = 8.8 cm

    PQ + QR = 5 cm + 3 cm = 8 cm < 8.8 cm

    or PQ + QR < PR

    So, the ΔPQR can not be constructed.
