Answer:
d = 13
Step-by-step explanation:
The distance formula in a complex plane is 
. Let us say that points (a,b) are (-2,-3) and points (s,t) are (3,9), both coordinates derived from given. Substitute the numbers into the equation to get the distance.
d = 
d = 13
Answer: 22
Step-by-step explanation:
By the triangle midsegment theorem, QR=2(US)=2(11)=22.
Since both angle are congruent (equal/same), which means that both side is equal to 40 degrees, we will put the equation like this:
5x - 5 = 40
Now we’ll solve for x:
5x - 5 = 40
+ 5 + 5 (Add 5 to both sides)
5x = 45
—- —— (Five both side by 5)
5 5
x = 9
Now we left with x, so x is equal to 9.
831.05, I think that is the correct answer
