Cosine is adjacent/hypotenuse, so the answer is A: 25/24.

Remember this: SohCahToa
Soh- Sine=opposite/hypotenuse
Cah- Cosine=adjacent/hypotenuse
Toa- Tangent=opposite/adjacent
Hope that helps!

Please answer asap this person made a mistake what is the error and correct solution to this problem

stiv31 [10]

Answer:

Step-by-step explanation:

Hello, please consider the following.

$(4+x)^2=4^2+2\cdot 4\cdot x+x^2=16+\boxed{8}x+x^2\\\\\text{ ... and not ...}\\\\16+\boxed{4}x+x^2$

So the correct equation becomes.

$x^2+64=16+8x+x^2\\\\8x=64-16=48\\\\\text{ we divide by 8 both sides of the equation.}\\\\x=\dfrac{45}{8}=6$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

A square outdoor patio with side length x feet is surrounded by a brick walkway that is 4 feet wide. What is the area of the wal

Masja [62]

Answer:

Area of walkway = 16(x+4) $ft^{2}$

Step-by-step explanation:

Length of the sides of the square outdoor = x feet

Area of the square outdoor = length x length

= x * x

= $x^{2}$ $ft^{2}$

The square outdoor is surrounded by 4 feet of walkway. So that,

length of the walkway = (x + 2(4))

= (x + 8)

Area of walkway with outdoor = (x + 8)*(x + 8)

= ( $x^{2}$ + 16x + 64) $ft^{2}$

Area of walkway = Area of walkway with outdoor - Area of the square outdoor

= ( $x^{2}$ + 16x + 64) - $x^{2}$

= 16x + 64

Area of walkway = 16(x+4) $ft^{2}$
