Answer:
Whats the question
Step-by-step explanation:
I dont understand the question for the problem

Substitute the values. 
Follow PEMDAS and multiply and divide first. 

Continue following PEMDAS and subtract. 
We know that sin(a-b) = sina.cosb - cosa.sinb
if a=70 & b=10 the sin(70-10) = sin(60) = √3/2
Sin70cos10-cos70sin10 = sin60 = √3/2
Answer:
The number of counties in state A = 56
The number of counties in state B = 58.
Step-by-step explanation:
Let the number of countries in state A = k
So, the number of state in state B = ( k+2)
(as he next consecutive even integer after k is k + 2)
Now, according to the question:
k + ( k+2 ) = 114
or, 2k + 2 = 114
⇒ 2k = 114 -2 = 112
⇒ k = 112/2 = 56
or, k = 56
Hence, the number of counties in state A = k = 56
and the number of counties in state B = k+ 2 = 56 + 2 = 58.
