Answer: The correct answer is: C) X, V and Y are collinear points.

Explanation: Three points being collinear does not do much in a similarity proof.

In order to prove similarity, we want to prove that all of the angles of one triangle are congruent to all of the angles of the other triangle.

The reflexive property showing an angle is congruent to itself helps do this.

The Corresponding Angles Postulate helps to prove angles are congruent.

A transversal can help prove angle congruence.

Collinear points will prove that angles sum to 180°, which will not help us prove similarity between triangles.

Temka [501]

Answer:

1.58

Step-by-step explanation:

So, we know there are 2.1 pounds, and for every pound it costs 0.75 dollars.

We can multiply the 2.1 by the 0.75 to find our answer.

The easiest way to do this is multiply the two numbers on 2.1 seperatly:

2 * 0.75 = 1.5

0.1 * 0.75 = 0.075

Then add them together:

1.5 + 0.075 = 1.575

Now we can round this to the nearest cent(hundreths place), and since the thousandths place is 5, we round up:

1.58

So our answer is $1.58!

Hope this helps!

PLEASE HELP ME ASAP!!! The diagonal of Andres rectangular TV screen is 39 in. The width of his TV screen is 34 inches. which mea

Y_Kistochka [10]

You can use the Pythagorean theorem to answer this. The diagonal is the hypotenuse of the right triangle that is formed. So, your equation will look like (h is height):
$34^2+h^2 = 39^2$

We have to solve for h:
$h^2 = 39^2-34^2$
$h = \sqrt{39^2-34^2}$

You can plug it into a calculator, and you get approximately 19.105. The answer closest to that is B. So, that's your answer! Hope it helps. If anything doesn't make sense, hmu!
