Answer:
true
Step-by-step explanation:
it is because 1 and 3 in set A are in sat B
By definition, the number 
is the ratio between the circumference and the diameter:
This implies that
And so your circumference is 
Answer:
1/3
Step-by-step explanation:
51/6 = 51/6
51/2= 5 3/6
= 2/6
Step-by-step explanation:
Question 10 :
3x + 6 = 4x – 12 ( reason: corresponding angles due to parallel lines)
simplify and get x, thus x = 18
to find 3x + 6 or 4x - 12(which is both the same),
3(18) + 6 = 60° , 4(18) - 12 = 60°
Question 11:
2x + 24 + x = 180 ( reason: interior angles due to parallel lines)
simplify again to get x, you will get x = 52
then find the individual by subbing in the value of x into the equation.
so 2x + 24 = 2(52)+24 = 128° and x = 52°
