Question

Can anyone answer any of these questions?

Answer 1

4) angle wpr is equal to angle arp because of alternate interior angles (remember WRAP is a parallelogram)

So:

x + 12 = 2x - 37

49 = x

Now plug in x = 49 for all four angles.

angle ARP = 61

angle WPR = 61

angle WRP = 29

angle APR = 29

So the two corners are both 90 degrees.  We can easily see that the other two corners are also 90 degrees, thus this parallelogram is also a rectangle.
