    True Bearing Question

    A bridge 11km connects city T in the south and City K in the north. THe true bearing of a ship is 120 degrees from T. The distance between S and T is 15km. Find the distance between the ship S and K to 1 decimal place.

    Ok so far I understand that the true bearing starts from true north, but I am anable to find out any more. Help please.

    HI

    Start measuring the bearing from the true north which you already know .

    then when you make a sketch , you will get a triangle KTS with , angle KTS =120 , KT=11 and ST =15

    so now you can use the cosine rule to find KS .
