Answer:
given mass =1500kg
intial velocity(u)=0 m/s
final velocity(v)=20m/s
time(s)=10 sec
accelerating force of the car engine=final velocity-intial velocity/time=20-0/10=20/10=2m/s^2
Let's call the width 
. Since the length is three more than the width, it is 
.
The area (which we know to be 70) is given by the multiplication of width and length:
To solve this equation, you can use the usual quadratic formula: given an equation 
, the two solutions are
which in your case becomes
So, two solutions are
Since we can't accept a negative length, we only accept the second solution.
So, the dimensions are 7 and 10
The area of the rectangle is 47 1/2
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

Answer:
I don't understand why this question is even on here. You literally just subtract. The difference is 18 degrees.
