Find the unknown angle measure by solving for the given variable.Answer Choices: 32,48,96,24,36,64

Answers

Answer 1

Answer:

A triangle is 180°. So you can do:

3.2n + 6.4n + 2.4n = 180 Simplify

12n = 180

n = 15 Now that you know the value of n, you can plug it into each individual angle/equation

∠X = 3.2n plug in 15 for n

∠X = 3.2(15)

∠X = 48°

∠Y = 6.4(15)

∠Y = 96°

∠Z = 2.4(15)

∠Z = 36°

Choose the converse of the following statement.They are not left behind, if they are on time.

If they are not left behind, then they are on time.
If they are on time, then they are not left behind.
If they are not on time, then they are left behind.
If they are left behind, then they are not on time

Answers

The converse of a statement can be found by switching the hypothesis and the conclusion (the beginning and ending statements) of a phrase.

Therefore, we started with the statement

"They are not left behind, if they are on time."

To find the converse of this statement, we just need to switch the position of the two pieces.

Therefore, the converse is

"If they are on time, then they are not left behind."

You answer is the above statement or the second option.

What are the area and perimeter of a rectangle?

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

We know the area of a rectangle is (length×width).

Given, His room is a rectangle, measuring 12 feet by 18 feet,

Therefore, The area of the room is

= (12×18) sq feet.

= 216 sq feet.

Also given one measures 3/4 inches by 2 inches.

Therefore the area of one tile is,

= [3/4×(2)] sq inches.

= 3/2 sq inches.

So, The number of tiles requires is the area of the room divided by the area of one tile which is,

= (216/(3/2)).

= 216×(2/3).
