Answer to A:

50%

Explanation for A:

We're looking for how many numbers are odd, so theres 1, 3, 5 ,7, four numbers.

We have a total of 8 numbers.

\frac{4}{8} = 0.5

To make any number a percent we move the point over to the right by two, which makes our final answer 50%

Answer to B:

37.5%

Explanation for B:

If the number is less than four, that means we need to find if it will roll the first three numbers. We, once again, have eight total possibilities

\frac{3}{8} = 0.375

0.375 can be turned into our final answer, 37.5%

If &lt;ABC measures 100 and is inscribed in a circle O. find &lt;BAO and &lt;BCO​
satela [25.4K]

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
