The answer is D. -3
you subtract x2 for x1 over y2 for y1 then you'll get 15/-3 then simplify the fraction
Hello,
Here is an analytic method.
Equation of the circle of center C(13,-31) and radius 37:
(x-13)²+(y+31)²=37²
x=25
We are going to calculate y
(25-13)²+(y+31)²=1369
==>(y+31)²=35²
==>(y=4 or y=-66)
So b=4 or b=-66
Answer:
11.5 m^2
Step-by-step explanation:
The area of a parallelogram is base * height, so you have to find the height.
You can see on the left there's a 30 - 60 - 90 triangle with a hypotenuse of 4. Using the proportion rule, you know that the 2nd side is 4/
=
.
Then, find the area, so do base * height = 5 *
=
.
Put this in a calculator and you get: 11.5 m^2
