Answer:
A would be correct.
Step-by-step explanation:
Just show that triangles AOB,BOC,COA are all congruent (then all the sides of triangle ABC must be equal). To show this, note that triangles A′BO,A′OC are equilateral since they are all radius of the circles. Line OA′ is perpendicular to line BC. Hence, ∠OBC=∠OCB=30∘.
The recursive formula 
means that the next term in the sequence is 5 more than the previous one.
So, we know that we start from 
, which means that the next term is
Similarly,
Answer:
Vertical Angles...............
Whole numbers are the numbers 0, 1, 2, 3, 4 and so on and negative numbers are not considered whole numbers.
natural numbers are called the counting numbers that are the numbers 1, 2, 3, 4, and so on. they are positive numbers and zero is not considered a natural number as you can see.
integers are all the whole numbers and their opposite (negative) but negative numbers are NOT whole or natural numbers. fractions and decimals are not integers.
rational numbers are numbers that include all the integers, plus all fractions, or terminating decimals and repeating decimals.
irrational numbers are an infinite number of digits to the right of the decimal point, without repeating.
so your answer is integer and rational, hope this helped! :)
The answer is
graph A
Hope this helps :)
