Can anyone answer any of these questions?

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.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
