Because this is a parallelogram, we know that the diagonals bisect. This means that AO = DO, and CO = BO
It doesn't matter which two segments we use, but I'm going to use CO = BO for this one.
3x - 7 = x - 1
2x = 6
x = 3
Option B. is the answer.
Answer:
135°
Step-by-step explanation:
(n-2) * 180 =
(8-2) * 180=
6*180= 1080
1080: 8 = 135
Answer:
Use the pythagorian theorm
Step-by-step explanation:
We can find this integer using a system of equations. The first thing we look at is the first sentence.
Let's call X The first integer,
Let's call Y the second integer.
So, X+Y=61 and X-Y= 1
Using Substituion on the second equation, we get
X=Y+1
(Now we plug in Y+1 into the second equation for X)
So,
(Y+1)+Y=61
2Y=60
Y=30
So, one of the integers is 30.
Now to find the second, we go back to
X=Y+1
X=30+1
X=31.
So, the integers are 31 and 30.
Hope this helps!
