    Parallelogram

    Guys I'm having a hard time solving this geometric problem given by my teacher


    Given : the figure is parallelogram
    Line T to S = 42cm
    Line A to C = 30cm
    Line U to S = 21cm

    I supposedly need to find the measure of Line B to S
    but my teacher gave already the measure which is (Line B to S = 24cm)
    but I need to know what is the procedure or formula on solving the measure of Line B to S

    Could someone help me please?

    I assume that there is a typo: The line \overline{SU} must be greater than the height of the parallelogramm.

    Could it be that you have mixed up \overline{SU} and \overline{AC}?

    would I get the right answer if I swap the value of AC and US ?

    if so , how did the BS became 24 ?

    enlighten me please

    I've made a sketch with the correct measures but I can't upload the GIF-file. So you have to make the drawing: As you can see the line BS must be greater than 24 cm.

    Maybe you can post the complete text of your problem, otherwise I am not able to help you.
