Three triangles are shown. x represents the measure of an angle, y represents the measure of its supplement, and a and b represent the measures of the other 2 angles. Which of the following statements is true for all three triangles?

x>y because a+b>y
x is greater than y because A plus b is greater than y

y>x because 180−x>a+b
y is greater than x because 180 minus x is greater than A plus b

x=(a+b)−180
x is equal to open paren A plus b close paren minus 180

y=180−(a+b)

assuming you mean addition: addition and subtraction are reverse operations.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
