Answer:
CD = 4
Step-by-step explanation:
I believe you know the geometric mean for altitudes?
CD = √AD * DB = √8 * 2 = √16 = 4
If you are not aware of this theorem, then use the similarity of triangles.
ADC ~ CDB
AD/DC = CD/DB (cross-multiply)
CD^2 = AD*DB,
CD = √AD * DB = √8 * 2 = √16 = 4
Answer:
x = 144°
Step-by-step explanation:
In the figure given , two regular polygons are given to us. Since the polygon has five sides , it is a regular Pentagon. We know that each angle of a regular Pentagon is 108° .
So , here as per figure two regular Pentagons are attached base to base . Now , we know that,
- Measure of complete angle is 360° .
- Measure of regular polygon's angle is 108°.
According to Question ,
⇒ 108° + 108° + x = 360°
⇒ 216° + x = 360°
⇒ x = 360° - 216°
⇒ x = 144°

Answer: 2.2% I’m not sure (ps. I’m really not sure like this is what I think it is butttt someone’s answer might be better so go with there’s)
Answer: OPTION B.
Step-by-step explanation:
Given the following System of equations:

You can use the Elimination Method to solve it. The steps are:
1. You can mutliply the second equation by -3.
2. Then you must add the equations.
3. Solve for the variable "y".
Then:

4. Now that you know the value of the variable "y", you must substitute it into any original equation.
5. The final step is to solve for "x" in order to find its value.
Then:

Therefore, the solution is:

The party was 5 hours. 353.86-200.51=153.35 then you divide that number by 30.67 and you get 5.
