# Thread: Parallelogram

1. ## 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 $\displaystyle \overline{SU}$ must be greater than the height of the parallelogramm.

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

3. 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.
