The answer is not 12.
The ratio of the arc to the angle equals the ratio of the circumference to 360°.
Then 3/30° = circumferece / 360°
3/30 = x / 360 => x = 360 * 3/30 = 36 units.
Answer: 36 units
When trying to prove that two triangles are congruent there are three congruency rules SAS, ASA and SSS. From the looks of things though I would say it would be the third one because just from the way you named the triangles I could tell that the two angles could correspond.
Answer:

Step-by-step explanation:

Coordinates of B
This question will be answered using line ratio formula;

In this case:



Solving for 
becomes



Comparing the right hand side to the left;
-- (1)
-- (2)
Solving (1)


Solving (2)


Hence;

Answer:
a). Mileage for carA=
, and mileage for carB=
b).total mileage for both is similar to average of them= 
=![\frac{5x+4}{2x(x+1)}[tex]mil/gal](https://tex.z-dn.net/?f=%5Cfrac%7B5x%2B4%7D%7B2x%28x%2B1%29%7D%5Btex%5Dmil%2Fgal)
Step-by-step explanation:
It is given that the distance traveled by car 
And distance traveled by car 
We know the mileage is mile/gallon,
a).So mileage of car

Similarly , the mileage for car


b).total mileage for both is similar to average of them= 

Now divide by 2 for total(average) mileage.
.
Thus those are the answers.
Answer:
A
Step-by-step explanation:
Adding a negative is the same as subtracting a positive
