Dicussion (1)

  • Joining SQ. In \(\bigtriangleup\) SPQ,

    (22o + a) + 55o + (41o + b) = 180o

    121o + a + b = 180o

    a + b = 180 - 121

    a + b = 59o.....(1)

    In \(\bigtriangleup\) SRPQ; R + a + b = 180o

    R + 59o = 180o

    (in (1), a + b = 59o)

    R = 180 - 59

    R = 121o
