Solve for X. Assume that segments that appear to be tangent are tangent Round to the nearest tenth as necessary.
DanielleElmas [232]

9514 1404 393

Answer:

  11.1

Step-by-step explanation:

The tangent makes a right angle with the diameter at the point of tangency. So, the triangle is a right triangle, and the Pythagorean theorem can be used to find the length of x. The radius is shown as 7.1, so the diameter will be 14.2.

  x^2 + 14.2^2 = 18^2

  x^2 = 122.36

  x = √122.36 ≈ 11.1

The length of the tangent is about 11.1 units.

Explain how estimating helps you check the reasonableness of your answer
Mumz [18]
It gets you closer to your answer.
Ex: 11×2-- Round 11 to 10 and then multiply and get 20. But if you get some answer like 50, you know it is wrong. But the answer is 23

daser333 [38]

Answer:

See below

Step-by-step explanation:

\frac{1}{1-cos A} - \frac{1}{1+cos A} =2 cosec A cot A \\  \\ L. H. S.= \frac{1}{1-cos A} - \frac{1}{1+cos A} \\  \\ = \frac{1+cos A - (1 - cos A)}{(1-cos A)(1+cos A)}\\  \\ = \frac{1+cos A - 1  +  cos A}{1-cos^{2}  A}\\  \\ = \frac{2cos A }{sin^{2}  A}\\  \\ =2 .\frac{1}{sin A}.\frac{cos A }{sin  A}.\\  \\  = 2.cosec \: A.cot \: A \\  \\  = R.H.S

Equality Properties

Step-by-step explanation:

<u>Step 1: Define</u>

0 = 4x + 4

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Subtract 4 on both sides:                    -4 = 4x
  2. Divide 4 on both sides:                        -1 = x
  3. Rewrite:                                                 x = -1

A pair of shoes cost $22.99 to make, the local store sells them for $36.99. What is the percent markup? (Round to the nearest hu
ASHA 777 [7]

C: 60.9% is the right answer

Step-by-step explanation:

The markup is calculated by using the formula

Mark\ up=Selling\ price-make\ price

Given

Make Price = $22.99

Selling Price = $36.99

So the mark up will be:

Mark\ up=36.99-22.99\\=\$14

Percent mark up will be:

Mark\ up=\frac{Mark\ up}{Make\ price}*100\\=\frac{14}{22.99}*100\\=0.6089*100\\=60.89\%

Rounding off to the nearest hundredth percent

60.9%

Hence,

C: 60.9% is the right answer
