Answer:

<CFD =62°

<AFB= 90°

Step-by-step explanation:

here you have a vertical angle, so to simply put it the answer on one side of the angle is the same answer for the opposite side of the angle. knowing this, angle <AFE is 62° and <CFD is on the opposite side making the angle the same(62°). the opposite angle of <AFB is <EFD which is 118° but both <AFB and <AFC equal 118° so you subtract 118° to <AFC degree which is 28° and you get 90°.

i hope this makes sense im not good at explaining. if anyone has a better explanation feel free to correct me.

malfutka [58]

<u>Answer</u>:

18 clips for $7.38 is the best value deal.

<u>Step-by-step explanation:</u>

An office is restocking office supplies. The table below shows the cost for the number of boxes of paperclips. We need to find what is the best value is.

To find the best value for money we can check the price of each paperclip.

To check the price of each paper clip we can use the following formula:

\text{Price of each paper clip} =\frac{\text { price of the box }} {{\text {number of clips in the box }}}

Now we can calculate the best value deal as follows:

\text{Price of each clip is box 1}=\frac{7.38}{18}=0.41$

\text{Price of each clip is box 2}=\frac{15.39}{27}=0.57$

\text{Price of each clip is box 3}=\frac{13.50}{30}=0.45$

\text{Price of each clip is box 4}=\frac{18.36}{36}=0.51$

\text{Price of each clip is box 5}=\frac{18.80}{40}=0.47$

So, from looking at the prices of each paperclip we can conclude that the 18 clips for $7.38 is the best value deal.

Work out size of angle x
myrzilka [38]

Answer:

Step-by-step explanation:

Comment

You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle

Equation

Cos(x) = a/c the way you have labeled it.

Givens

a = 9

c = 18

Solution

Cos(x) = a / c

Cos(x) = 9 / 18

cos(x) = 1/2

x = cos-1(1/2)

x = 60 degrees

Answer

x = 60
