A certain television is advertised as a 17-inch TV (the diagonal length). If the width of

Vitek1552 [10]

Answer:

15 inches

Step-by-step explanation:

We can solve this problem using the Pythagorean theorem. The formula is:

$a^{2} + b^{2} = c^{2}$

where 'c' is the hypotenuse (the longest side) and 'a' and 'b' are the legs (the other sides).

First, draw a diagram for the problem. (See the photo attached below)

We know the other leg is 8 and the hypotenuse is 17. 'a' is the missing side.

a = ?

b = 8

c = 17

Substitute the values into the equation.

$a^{2} + b^{2} = c^{2}$

$a^{2} + 8^{2} = 17^{2}$

Rearrange to isolate 'a'

$a^{2} = 17^{2} - 8^{2}\\$ Square root both sides

$a = \sqrt{17^{2} - 8^{2}}$ Square each number

$a = \sqrt{289-64}$ Subtract under the root

$a = \sqrt{225}$ Find the square root

$a =15$ Final answer

Therefore, the TV is 15 inches tall.

AB=AD and BC=DC. B 35 Ax 82°C x = [ ? ]° Enter

melamori03 [73]

Answer:

y = 49°

Step-by-step explanation:

∠DBC = ∠CBD { BC = DC ; angles oppostie to the equal sides are equal}

∠DBC + ∠CBD + ∠C = 180 {angle sum property of triangle}

y + y +82 = 180

2y = 180 - 82

y = 98/2 = 49

I need help plz, percents

professor190 [17]

14.
$\frac{32}{128} = \frac{x}{100} \\ x = \frac{32 \times 100}{128} \\ x = 25$
15.
$\frac{3}{36} = \frac{x}{100} \\ x = 8.3$
16.
$\frac{30}{100} = \frac{23.7}{x} \\ x = \frac{23.7 \times 100}{30} \\ x = 79$
17.
$\frac{7.5}{100} = \frac{12}{x} \\ x = \frac{12 \times 100}{7.5} \\ x = 160$

please mark as brainliest answer.
