The frequency of waves are determined by the amount of waves that pass a specific point in a certain period of time and Radio stations broadcast their signals at different frequencies so that the range of radio frequencies can be used by many stations.
Answer: 15 and 16
Explanation:
You can set up an equation N is one positive integer, and N+1 is the second (because they are consecutive, so it's the first number plus one).
Equation to solve for N
N(N+1) = N + (N+1) + 209
N^2 + N = 2N +1 + 209
N^2 - N - 210 = 0 (factor here)
N = 15 or N = -14
Since the question asks for the positive integers, you know the first number is 15, then the next would be 16.

I'm assuming you're comparing two triangles? If not, then this is probably wrong.
Triangle = 180 degrees
180 divided by 3 = 60 degrees
since ∠1 ≅ ∠2 ≅ ∠3, each angle equal 60 degrees
∠4 ≅ ∠5
m∠4 = m∠3 + 10
m∠3 + 10 = m∠5
we know that m∠3 is 60 degrees.
60 + 10 = 70, so m∠5 is 70 degrees
70 degrees is the answer.
