Answer:

True

Step-by-step explanation:

It's given by the problem that the two triangles are similar. Similar polygons have congruent angles and proportional sides. Thus, corresponding angles between these two triangles are congruent. Since angle A and angle D correspond, they are congruent.

The distance between two points is 6_/6.One endpoint is (4,-1). It is known that the y-coordinate of the other endpoint is 9.

babunello [35]

The x-coordinate of the given endpoint will be " $x = 4 \pm 2\sqrt{29}$ ".

According to the question,

The end points are:

$(x_1,y_1) = (4,-1)$
$(x_2, y_2) = (x,9)$

Distance,

$6\sqrt{6}$

As we know,

The distance formula,

→ $Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

By substituting the values, we get

→ $6\sqrt{6} = \sqrt{(x-4)^2+(9+1)^2}$

→ $216= (x-4)^2+100$

→ $(x-4)^2 = 116$

→ $x-4 = \pm \sqrt{116}$

→ $x-4=\pm 2\sqrt{29}$

→ $x = 4 \pm 2\sqrt{29}$

Thus the above answer is right.

What is 2 1/8 take away 1/2

goblinko [34]

The equation is $2\frac{1}{8} - \frac{1}{2}$ .

1/2 is equivalent to 4/8, and 2 1/8 is equal to 17/8. (two full sets of 8 + 1 = 8 + 8 + 1, or 17)

The new equation is $\frac{17}{8} -\frac{4}{8}$ . Subtract the numerators.

17 - 4 = 13 or 13/8

The improper fraction $\frac{13}{8}$ simplifies to $1\frac{5}{8}$ .

<h2>Answer:</h2>

$1\frac{5}{8}$

Hope this helps :)

Suppose account numbers for an internet service provider consist of alpha-numeric characters. The first character is a digit (0

Amiraneli [1.4K]

Answer:

20,442,240 account numbers are possible.

Step-by-step explanation:

The first character has 10 possible values.

The next 2 has 26 * 26 = 676 possible combinations.

The last 4 has 9*8*7*6 = 3024 possible combinations.

So the answer is 10 * 676 * 3024

= 20,442,240.
