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

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 $\overline{AC}$?

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

if so , how did the BS became 24 ?
