Answer:

AC = 16 in.

Step-by-step explanation:

AD = CD = 10 in.

BD = 6 in.

AC = 2(AB) = ?

Apply pythagorean theorem to find AB

AB² = AD² - BD²

Substitute

AB² = 10² - 6²

AB² = 64

AB = √64

AB = 8

Therefore:

AC = 2(AB) = 2(8)

AC = 16 in.

Given right triangle ABC. To the nearest degree, find the measure of angle B.

DedPeter [7]

Answer:

Step-by-step explanation:

We have the length of AC which is opposite angle B; we also have the length of the hypotenuse. We will use trig here to solve for angle B. The sin ratio is the one that fits.

sin(B) = side opposite / hypotenuse:

$sin(B)= \frac{ 4.8}{ 5.1}$ so

sin(B) = .9411764706

Now we will use the 2nd button on our calculators. This will give us the missing angle value. Press 2nd then sin and you will see on your screen:

$sin^{-1 ($

Enter that decimal after the open parenthesis and hit "enter" to get

B = 70.25 or 70°

The ratio of the number of fiction book is 9:4, the different between the number of fiction and non fiction is 245

Evgesh-ka [11]

Answer:

Step-by-step explanation:

The ratio of the number of fiction books is 9:4

the difference between the number of fiction and nonfictionn is 245

so if the number of fiction books = 9x

then the number of nonfiction books = 4x

then difference = 9x-4x = 5x

the difference is given 245

then 5x= 245

x= $\frac{245}{5}$ =49

number of fiction books =49×9=441

number of nonfiction books =49×4=196

Someone help me please?! Math problem!!!

Gala2k [10]

Answer:

y = 4/5x - 9/5

Step-by-step explanation:

4x - 5y = 9 to solve for y you get it by itself.

-4x -4x minus 4x from both sides

-5y = - 4x + 9

/-5 /-5 Divide both sides by 5

y = 4/5x - 9/5 because -4/-5 is 4/5 and 9/-5 is - 9/5
