PQ is a vertical tower 95m high, the points R and S are on the same horizontal plane as Q, the angle of elevation of P from R is 35 if QS =155m and Q from RQS=48
1.Calculate the distance of QR
2.Calculate the distance of RS
3.Calculate the are of QRS

  • math -

    1. tan35 = 95/QR
    QR = 95/tan35 = 136.

    2. RS = 155 - QR = 155 - 136 = 19.

    3. What do you mean by "the are of QRS"?
