Answer:

The prime number 2.

Step-by-step explanation:

Odd number + Odd number = Even number

An odd number plus another odd number equals an even number. And most prime numbers are odd, so you might think this is true. Is it?

Wrong. The prime number 2 is an even number and

Even number + Odd number = Odd number

Odd number + Even number = Odd number

So, there is a number that can make the sum of two prime numbers odd.

Mara is building a set of shelves supported by a diagonal brace, as shown in the diagram. Answer the questions to decide whether

Kazeer [188]

Answer:

Step-by-step explanation:

1). Since, m∠1 + m∠2 = 180° [Supplementary angles]

If m∠2 = 120°

m∠1 + 120° = 180°

m∠1 = 180° - 120°

m∠1 = 60°

2). If a transversal intersects two parallel lines on the top and middle,

∠1 and ∠5 will be corresponding angles.

3). Since, m∠1 = m∠5 = 60° (Corresponding angles)

Therefore, both the lines on top and middle will be parallel.

4). Since, m∠9 + m∠11 = 180° [Supplementary angles]

If m∠11 = 120°

m∠9 + 120° = 180°

m∠9 = 60°

Since, m∠1 = m∠9 = 60° [Corresponding angles]

Therefore, both the lines on the top and bottom shelves will be parallel.

5). Since, m∠5 = m∠9 = 60° [Corresponding angles]

Therefore, middle and bottom shelves will be parallel.
