    To be really very honest, The initial music is very harsh Sir, basically before watching the lecture I personally get annoyed please change this it should be positive and pleasant to the ears, otherwise your videos are very informative and I always visit to your channel for conceptual clarity. Hope it is conveyed to you in the positive way.

    In Q3 where we know area =1/2(ab)(sin ¤)
    Thus area =3_/3
    So cant we put in our old formula
    1/2(base*height) =area
    Thus , 3_/3 = 1/2 * ( 4+3 ) * height
    Thus final height is (6_/3)/7
    *** i got that 7 by doing 4+3 becoz of the concept of angle bisector
    So why cant this be the answer 🤔

    so BD= sin30*4= 2;
    now tan 30= BD/AD;
