These angles are known as corresponding angles and when added up, they must be equal. So, let's set them equal to that, so we can solve for x, and then angle ABC:

$2x+46=3x-2$

$46=x-2$

$x=48$

Find ABC:

$2(48)+46 = 142$

As per to my calculations, ∠ABC = 142°.

Are the irrational numbers closed under addition?

Arte-miy333 [17]

Answer:

Irrational numbers are not closed under addition.

Step-by-step explanation:

Irrational numbers are the numbers that cannot be expressed in the form of a fraction $\frac{x}{y}$ . In other words we can say that irrational number,s decimal expantion does not cease to end.

The closure property of addition in irrational numbers say that sum of two irrational number is always a rational number, But this is not true. It is not necessary that the sum is always irrational some time it may be rational.

This can be understood with the help of an example:

let (2+√2) and (-√2) be two irrational number. Their sum is (2+√2)+(-√2) = 2, which is clearly a rational number.

Hence, irrational numbers are not closed under addition.
