It's the right angle. The circumcenter is in half of hypotenuse.
The formula of a midpoint of segment BC:
We have the points B(-2, -2) and C(7, -5). Substitute:
Answer: (2.5, -3.5)
Answer:
a = -15.5, b = -32.5
Step-by-step explanation:
Let's say the first number is a, and the second is b.
a + b = - 48
a - b = 17
If you add both equations, you get 2a = -31, because the
+b and -b cancel each other.
So you would get a + a = 2a, then -48 + 17 = -31
2a = -31
--- ---
2 2
Divide both sides by 2 to get a by itself.
a = -15.5
Then let's go to the next equation (a - b = 17)
Plug in a..
-15.5 - b = 17
+ 15.5 + 15.5
------
-b = 32.5
--- ------
-1 -1
b = -32.5
Hope this helps.

Hello!
We can find the area of the trapezoid using the formula for area of a trapezoid:
FORMULA:
A = [(b + b) * h / 2]
SUBSTITUTE:
A = [(13.5 + 27.5) * 14 / 2]
SOLVE:
A = 41 * 14 / 2
A = 574 / 2
A = 287 cm²
So, the area of the trapezoid is 287 cm².
Answer:
-700½ meters or -700.5 meters
Step-by-step explanation:
Usually, the depths below the ground are denoted by the minus sign.
Seven hundred and five-tenths meters mean 700+(5/10) which is equal to 700+1/2. So, the answer becomes -700½ meters or -700.5 meters.
