BDC=142
Answer:
Step-by-step explanation:
Review the standard equation of a circle with center at (h, k) and radius r:
(x - h)^2 + (y - k)^2 = r^2
A point on (4, -2) has the radius r^2 = (4)^2 + (-2)^2, or r^2 = 20, or r = 2√5. Knowing the center is at (0, 0), we can write:
x^2 + y^2 = 20, or x^2 + y^2 = (2√5)^2
Answer:
mABD=24
mDBC=24
Step-by-step explanation:
First, set up x+15 and 4x-12 as equivalent equations
Subtract x from both sides to get 3x-12=15
Add 12 to get 3x=27
x=9
Plug 9 into the original equations representing the measurements of angles
You should get 24 for both because bisected means both are congruent
Answer:
2
Step-by-step explanation:
2/3x + 8/3 = 2x
multiplicate each by 3 : 2x + 8 = 6x
Put all the x on the same side : 8 = 4x
divide each by 4 : 2 = x
x = 2
Hey there!
The answer would be 4 FEET. If the slide is 10 feet tall and you are 6 feet down the slide then your are only 4 feet high. Just simple subtraction! So x = 4.
Hope this helps!
