From the picture we can see that angles Z and X are the same because they are oposite angles of parallelogram and rule for it is that oposite angles are the same.
so we can write that equations for determining their size are the same
7x + 61 = 9x + 47
Now we just solve for x.
2x = 14
x = 7
If we implement this in formula for Z we find:
Z = 7*7 + 61 = 110
we implement value of x in the lenght of WY as well
WY = 84 - x = 84 - 7 = 77
Answer is C

B. x-2y=6
Step-by-step explanation:
Answer: 20
Step-by-step explanation: 5 times 4 is 20 times 2 is 40, but when you divide by 1/2 you drop down to 20.
Answer:
3.14×4÷5
Step-by-step explanation:
multiply 3.14 by 4 then divide that answer by 5
Answer:
<em>x + 11 is an </em><em>even number</em><em>.</em>
Step-by-step explanation:
Even numbers can only be obtained from the sum of two odd numbers or two even numbers. Since we know that x + 7 is even, x + 11 <em>must</em> be even as well.
