A=32, B=32, C=148, D=148
A parallelogram has 2 sets of equal angles and the total sum of all angles is equal to 360
Angles A,B are 32, to work out CD add angles AB then subtract that from 360
=360-64
=296
To work out each angle (CB) divide that by 2, therefore C and D are 148

The best design for this study is to do an independent and dependent experiment of the outcomes from different types of soils for tomato plants.
Are you supposed to shade something in? or find out the overall area of the thing?
Let ∠RTS=∠RST = a (say)
∠QUA=∠QSU= b(say)
then we know , at point S, a+40+b=180. so, a+b=140 we'll use this later.
consider trianglePQR, ∠P+∠Q+∠R=180
i.e.P+(180-2b)+(180-2a)=180
P+180+180-2(a+b)=180 ⇒P+180-2(a+b)=0 ⇒P=2(140)- 180=280-180=100
hence,answer is E
