QR is the median of the trapezoid, so its length is the average of the top and bottom bases. Write that. Say (length of QR)=1/2 of (length of the top + length of the bottom). That gives you a nice simple equation that you can easily solve for 'x'.
Answer:
Step-by-step explanation:
4y - 16 + 68 = 180
4y + 52 = 180
4y = 128
y = 32
2x - 24 = 68
2x = 92
x = 46
89 is prime 16 is composite 17 is prime 25 is composite
