In this diagram, what is ac?

Answers

Answer:

AC = 10 units .

Step-by-step explanation:

Given : Triangle ABC.

To find : What is AC.

Solution : We have given Triangle ABC.

Triangle BCD is right angle triangle .

By the Pythagorean theorem :

$(BC)^(2) = (BD)^(2) + (CD)^(2)$ .

Plug the values .

$(17)^(2) = (BD)^(2) + (8)^(2)$ .

289 = $(BD)^(2) + 64$ .

On subtractin g 64 from both sides.

289 - 64 = $(BD)^(2)$ .

225 = $(BD)^(2)$ .

Taking square root .

BD = $√(225)$ .

BD 15 units .

AB = AD+ BD

21 = AD + 15

AD = 21 -15

AD = 6 units .

Now , Triangle ACD is right angle triangle .

$(AC)^(2) = (6)^(2) + (8)^(2)$ .

$(AC)^(2) = 36 +64$ .

$(AC)^(2) = 100$ .

Taking square root

AC = 10 units .

Therefore, AC = 10 units .

$\sqrt{17 {}^(2) { - 8}^(2) } = 15 \n 21 - 15 = 6 \n \sqrt{8 { }^(2) } + √(6 ) {}^(2) = 10 \n c.10$

Which expression is equivalent to the given expression? 13x – 29x A. 13(x + 29) B. x(13 – 29) C. 13(x – 29) D. x(29 – 13)

Answers

The answer I got is, B. x(13-29) I hope this helps you.

Answer:

It is b, the expression is multiply the variable by 13-29 :)

Answer:9^5

Step-by-step explanation:

A triangle has the following side lengths: 8 centimeters, 13 centimeters, 15 centimeters. Which of the following statements best describes its construction? It is impossible to construct a triangle with these side lengths. There is one possible triangle with these side lengths. There are many possible triangles with these side lengths. There are many possible similar triangles with these side lengths.

Answers

Answer:

The statements that best describes its construction is:

There is one possible triangle with these side lengths.

Step-by-step explanation:

We know that with the help of three given angle measures infinite number of triangles could be constructed with different side lengths and with the help of three gives side lengths a unique triangle is constructed.

Here we are given three side lengths as:

8 centimeters, 13 centimeters, 15 centimeters.

This means that there is only one such triangle possible.

I am not completely sure but I would think it would be the second statement. Hopes this helps.
