First, find the arc measure BD. The arc measure is twice the central angle measure. BD should be 48*2 = 96.

The chord BC looks like it’s the diameter of the circle, so it must have a measure of 180.

From here you can find DC. The total measure of a circle is 360.
360- 96-180 = 84, so DC is 84.

DBC is 360- DC
so 360- 84 = 276.

DCB is just 360- BD
so 360- 96 = 264.
Hope this helps!

Ik this is late, but people who are looking for the answer can see this.

Answer:

an =1/3*6^n-1

Step-by-step explanation:

You should plug in 2 for n in each equation, which, the correct one should give you 2. Then, to make sure, you plug in 3 in the equations that gave you 2.

Example:

an = 1/3 * 6 ^n-1

Plug in 2.

an = 1/3 * 6 ^2-1

an = 1/3 * 6 ^1

1/3 * 6 = 2

Step 2.

an = 1/3 * 6 ^3-1

an = 1/3 * 6 ^2

1/3 * 36 = 12

Hope this helps.

Which of the following statements are never true? Select all that apply. Three points are coplanar Two planes meet in exactly on
statuscvo [17]

Answer: Two planes meet in exactly one point

Two lines meet at exactly two points


Step-by-step explanation:

From the given statements there are two statements which are never true :-

1) Two planes meet in exactly one point .

Since when two line meets , they either meet at one point or infinite points (coincidence) , thus its impossible that they will meet at exactly two points.

2) Two lines meet at exactly two points

Since when two planes meet , the intersection of two plane always make a line not a point. Thus its impossible.
