Answer:
The measure of arc AC is 85°
Step-by-step explanation:
we know that
The inscribed angle measures half that of the arc comprising
so
m∠ABC=(1/2)[arc AC]
substitute
(4x-5.5)°=(1/2)[5x+25]°
(8x-11)°=(5x+25)°
8x-5x=25+11
3x=36
x=12°
Find the measure of arc AC
arc AC=(5x+25)°
arc AC=5(12)+25=85°
The mean is 250.875.
Using this information, I can put the following into a calculator:
√(((250.875-195)²+(250.875-358)²+(250.875-201)²+(250.875-276)²+
(250.875-161)²+(250.875-301)²+(250.875-387)²+(250.875-128)²)÷8)
Which equals:
87.9878

Answer:
W = 16
L = 24
Step-by-step explanation:
Let's write down the information we have first
"The length of a rectangle is 8 feet longer than it is wide"
L = W + 8
"If each side is increased 8 feet, then the area is multiplied by 2."
(L + 8)(W + 8) = 2LW
Now we can solve for W first, then L
(W + 16)(W + 8) = 2W(W + 8)
W² + 24W + 128 = 2W² + 16W
0 = W²- 8W - 128
0 = (W - 16)(W + 8)
W = 16
L = 24
(This part above is solved like quadratics)
