Identify the similar triangles them find the x

Alex Ar [27]

Answer:

ADB and ABC are similar

x = 8

Step-by-step explanation:

hypotenuse in ADB = $\sqrt{4^2 + 2^2 } = \sqrt{20}$

since two triangles are similar,

$\frac{2+x}{\sqrt{20} } = \frac{\sqrt{20}}{2}$

solving for x, x=8

The perimeter of a rectangle swimming pool is 160 feet. The length of the swimming pool is four times its width . Find the dimen

Helga [31]

Formula for Perimeter of Rectangle:

P = 2(L + W)

Plug in 160:

160 = 2(L + W)

L = 4W
<span>So we can plug in '4W' for 'L' in the first equation.</span>
<span>160 = 2(L + W)

160 = 2(4W + W)

Combine like terms:

160 = 2(5W)

160 = 10W

Divide 10 to both sides:

W = 16

Now we can plug this back into any of the two equations to find the length.

L = 4W

L = 4(16)

L = 64

So the width is 16, and the length is 64.</span>

Geri believed the answer to one of her homework problems was 2 cubed. After checking her work, she realized the correct answer w

TiliK225 [7]

Answer:

The correct answer is 64 times Geri’s original answer

Step-by-step explanation:

Given

Gari's Answer: 2³

Correct Answer: 2⁹

Required:

Relationship between both answers

Let Gari's answer be represented by G and the Correct answer be represented by C; Such that

G = 2³

C = 2⁹

Divide C by G

$\frac{C}{G} = \frac{2^9}{2^3}$

From law of indices, $\frac{a^m}{a^n} = a^{m-n}$

Applying this law, we have

$\frac{C}{G} = 2^{9-3}$

$\frac{C}{G} = 2^{6}$

$\frac{C}{G} = 2*2*2*2*2*2$

$\frac{C}{G} = 64$

Multiply both sides by G

$G * \frac{C}{G} = 64 * G$

$C = 64G$

Hence, we can conclude that the correct answer is 64 times Geri’s original answer
