Since the angle are both 45 degrees, then you know that both legs are equal=12.
so to find the hypotenuse, you use the pythagorean theorem:
12^2+12^2= c^2
144+144=c^2
288=c^2
square root(144) x square root (2)=c
12 square root 2 is the answer, so D.
Since the properties of a rhombus tells us that both pairs of opposite sides are congruent we can therefore conclude that DB will be 12
Hello from MrBillDoesMath!
Answer: 1/12
Discussion:
We solve 5/12 + x = 1/2 for x. Begin by subtracting 5/12 from each side
5/12 - 5/12 + x = 1/2 - 5/12
0 +x = 6/12 - 5/12 (as 1/2 = 6/12)
So x = 1/12

Answer:
1 1/12
Step-by-step explanation:
b-7/4=-2/3
First, in an equation like this, you add 7/4 to each side which will look like this:
b-7/4=-2/3
+7/4=+7/4
We add 7/4 to each side of the equation to balance the numbers.
b=+7/4-2/3 (because the minus symbol is in front, we put that)
Before adding we have to find the least common denominator known as LCD.
We find that by first looking at the denominators or the fractions which are 4,3
4,8,\12/,16,20,24.
3,6,9,\12/,15,18,21,24.
We can also find the LCD by multiplying 3 and 4. As you can see in the list, there are 12's in each list of numbers. We use that to change our fractions.
From the number 4 we find out how many times (x) we have to add 4 to get 12. We do 12/4 which is 3. And 12/3 which is 4.
7 x 3 2 x 4
------- - -------
4 x 3 3 x 4
which equals 21/12-8/12. Now that we have a common denominator, we can subtract.
21 8 13
--- - --- = ----- = 1 
12 12 12
I hope this helps, please let me know if I have any incorrections. :D
