Answer:
<BCO = <BAO = 20degrees
Step-by-step explanation:
If <ABC measures 100 and is inscribed in a circle O. find <BAO and <BCO
To get <BAO and <BCO, we need to get <AOC first.
From the figure, it can be seen that triangle ABC is an isosceles trinagle. Hence;
<BAC + <BCA + 100 = 180
Since <BAC = <BCA
<BAC + <BAC = 180 - 100
2<BAC = 80
<BAC = 80/2
<BAC = 40
Also;
<BAO = <BCO and <BAO = <BAC/2
<BAO = 40/2 = <BCO
Hence <BCO = <BAO = 20degrees
Answer:
Correct option: c)
radius = 6 inches
Step-by-step explanation:
The complete arc of a circumference has 360 degrees, and the length is 2*pi*radius
Knowing this, we can use a rule of three to solve this problem:
144 degrees - > 15 inches
360 degrees -> 2 * pi * radius
144/360 = 15/(2pi*radius)
2pi*radius = 360 * 15 / 144
radius = 37.5/(2pi)
radius = 5.9683 inches
Rounding to nearest whole number, we have radius = 6 inches
Correct option: c)
