The points A and B and the center O of the circle form a right angle and AO = radius.
So by Pythagoras
16^2 = 15^2 + AO^2
AO = sqrt (16^2 - 15^2)
AO ( radius) = sqrt31 = 5,57 feet answer (to nearest hundredth)

Answer:
Correct option: A
Step-by-step explanation:
The angle BDC inscribe the arc mBC, so we have that:
mBDC = (1/2) * mBC
mBDC = (1/2) * 118 = 59°
From the secants relation in a circle, we have that:
mA = (1/2) * (mBC - mDE)
35 = (1/2) * (118 - mDE)
70 = 118 - mDE
mDE = 48°
The sum of the arcs is 360°, so we have:
mBC + mCD + mDE + mBE = 360
118 + mCD + 48 + 76 = 360
mCD = 360 - 118 - 48 - 76 = 118°
The angle mCBD inscribes the arc mCD, so we have:
mCBD = (1/2) * mCD = (1/2) * 118 = 59°
The angles mCBD and mBDC are equal, so the triangle is isosceles.
Correct option: A
Answer:
$0.99
Step-by-step explanation:
2 L costs $1.98
so all we have to do is divide it by 2 to find out 1 L.
$1.98 divided by 2 is $0.99.
Answer:
Mean: 3 Mad: 1/3
Step-by-step explanation:
First we need to find out the numbers, so to get a mean of 3 we have to get to 9 ebcause there are 3 arrows.
- We have to make sure that the arrows are not too close to the center
- You can have decimals
2nd: Once you find the numbers which are 2.5, 3, and 3.5 you add them together and divide it by 3 to get 3 the mean
3rd: Find the MAD but adding .5 and .5 to get 1 then divide it by 3 and you get 1/3 as the MAD.
Hope this helps!
