Find the value of x.

Answer:

Step-by-step explanation:

I realize that the time is passed.... but FYI

BD is <u><em>Geometric Mean</em></u>

That's mean BD² = 6 × 5 = 30 ⇒ BD = √30

x² = BD² + 6² = 30 + 36 = 66 ⇒ x = √66

y = √55

Adaline is designing a garden in the shape of a 45º-45º-90º triangle, with an area of 32 ft2. To the nearest foot, how much fenc

wel

Answer:

27 ft

Step-by-step explanation:

Given: A garden in the shape of a 45º-45º-90º triangle.

Area of triangle= 32 ft²

As given dimension of triangle, we understand that it is a right angle and triangle and since two angles are equal, therefore two sides of triangle are also equal.

∴ Base and height will be equal.

Assuming base is also as "h"

Now, finding the length of base and height by using area of triangle formula.

Area of triangle= $\frac{1}{2} \times base\times height$

⇒ $32= \frac{1}{2} \times h\times h$

Multiplying both side by 2

⇒ $64= h^{2}$

Square rooting both side, remember; √a²= a

⇒ $\sqrt{64} = h$

∴ h= 8 feet

Hence, both base and height of right angle triangle is 8 feet.

Next, finding total fencing required to enclose the garden.

Perimeter of garden is equal to the amount of fencing required by Adaline.

Therefore, finding the length of hypotenous of triangle too.

Using pythogorean theoram.

$h^{2} = a^{2} +b^{2}$ , where a is the height and b is the base of triangle.

⇒ $h^{2}= 8^{2} +8^{2}$

⇒ $h^{2} = 128$

Square rooting both side

⇒ $h= \sqrt{128}$

∴ h= 11.3 feet

Perimeter of garden= $base+height+hypotenous$

⇒ Perimeter of garden= $8+8+11.3= 27.3\ feet$ $\approx 27\ feet$

Hence, 27 feet fencing is required to enclose the garden.

Someone please help me on this question ?:)

katrin2010 [14]

Answer: The TV is 48 inches wide.

Step-by-step explanation: To find the solution to this equation we must use the Pythagorean theorem. The Py. Theo. is basically the formula :

a^2 + b^2 = c^2 You say this as "A squared plus b squared equals c squared"

To use this formula you must plug in the given values of a and b, to find c. A and b represent the two bases of the triangle, while c is the hypotenuse. In this equation we already have the value of c and a. We need to find b, but in order to do that we use a different formula. We use : c^2 - a^2 = b^2

See :

52^2 - 20^2 = b^2 *The ^2 means "to the power of" aka an exponent*

2704 - 400 = b^2 *When dealing with ^2, all you do is multiply the number by itself*

2304 = b^2 *Next, we find the square root of our current number.*

48 = b

*Another way to solve this equation is to memorize all the Pythagorean Triples. With that knowledge, you wont even need to use the formula because you will already know all three values. I hope this helped you understand :)
