Since ABC is equal to DCB, you can use the angles given in triangle ABC in triangle DCB. Since the sum of the angles in a triangle is 180, the equation would be this:
90+46+x=180
Solve for x in that and you're good :)
Answer:
350 divided by 70
Step-by-step explanation:
350 by 5= 70 350 by 70 = 5
Hope this helps
0.30 or if u flip it around it would be 43/13=3.30
Hello there!
First, let's take a look at what the formula for the circumference and area of a circle is.
The circumference is "2

r", or "2 * 3.14 * r".
The area is "

r^2", or "3.14 * r * r".
Let's establish what the radius is, as

is equivalent to 3.14.
The radius is half of the diameter, and our diameter is 10.
Divide 10 by 2 to find our radius.
10 / 2 = 5
The radius is 5.
Now, let's plug in 5 for the radius for both formulas.
C = 2 * 3.14 * 5
10 * 3.14
31.4 is our Circumference.
Now, onto the area.
A = r * r * 3.14
5 * 5 * 3.14
25 * 3.14
78.5 is our Area.
I hope this helps!
Answer:
y=2
x=7
Step-by-step explanation:
subtract equation 1 from 2
0+2y=4
y=2
substitute y into equation 1
x+2=9
x=9-2
x=7
