Answer:
B
Step-by-step explanation:
The central angle ANC is equal to the arc ABC that subtends it, thus
arc ABC = 138° → B
Let
x-------> the number of dinner
y-------> the number of lunch
we know that
-------> equation A
------> equation B
Substitute equation B in equation A
![8[y]+5y \leq 42](https://tex.z-dn.net/?f=8%5By%5D%2B5y%20%5Cleq%2042)



so
the greatest number of lunch is 

Hence
the greatest number of dinner is 
therefore
the greatest number of meals is

<u>the answer is</u>

Answer:
132
Step-by-step explanation:
corresponding angles are the same
We know that to angle A coresponding side a and to angle B corespond side b so there given that to angle A with measure of 30 degree corespond the side length of side a = 2 but from this given details that side b has length equal 2 so from this reasult that the measure of angle B is equal 30 degrees too same with angle A
Answer:
the final answer is 63.612200038757
