Answer:

<h2><u>x = 8.2</u></h2>

Step-by-step explanation:

A^2+B^2=C^2 is the pythagorean theorem to find a missing siede of a triangle.

First triangle on the right:

5^2+B^2=10^2

25+B^2=100

B^2=75

B=8.66025404

B=8.7

Second triangle of left:

3^2+B^2=8.7^2

9+B^2=75.69

B^2=66.69

B= 8.16639455

B=8.2

x=8.2

Rachel bought 3 CDs that were each the same price. Including sales tax, she paid a total of $35.40. Of that total, $2.70 was tax
kotegsom [21]

Answer:

Step-by-step explanation:

Total bill - the tax = cost of 3CD's

Our total bill is $35.40, the tax is $2.70, therefore,

35.40 - 2.70 = cost of 3 CD's so

3 CD's = $32.70

Divide that by 3 to get the cost per CD:

32.7 / 3 = $ 10.90 per CD

<span>(A) Find the approximate length of the plank. Round to the nearest tenth of a foot.
Given that the distance of the ground is 3ft.
In order to get the length of the plank,
we can use the this one.

cos 49 = ground / plank
cos 49 = 3 / plank
plank = cos 49 / 3
plank = 0.10 ft

</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
The remaining angle is equal to
angle = 180 - (90+49)
angle = 41

Finding the height.
tan 41 = height / ground
tan 41 = height / 3
height = tan 41 / 3
height = 0.05 ft.

(A) 0.10 feet
(B) 0.05 feet</span>
