Answer:

x = 20

Step-by-step explanation:

<u><em>Given:</em></u>

<em>AB , CD, EF are straight lines</em>

<u><em>To Find:</em></u>

<em>Find the value of x</em>

<u><em>Solve:</em></u>

<em>Let the point of intersection of the lines AB, CD and EF  be O.</em>

<em>Therefore,     {Opposite angles }</em>

<em>∠ </em>AOE= ∠ BOF=3x^o

<em>∠</em>COF= <em>∠ </em>EOD=4x^o

<em>∠</em>BOD= <em>∠ </em>AOC=2x^o

Note:

Sum of all angles = 360 degree

Since we know that sum of all angles equals to 360 degree.

Hence,

2(2x ^o )+2(4x ^o )+2(3x ^o )=360 ^o         {Simplify}

18x^o=360^o            {Divide each side by 18}

x=20

So the value of x equal 20

How can I solve this does anyone knows?
Ipatiy [6.2K]
A. C = 17h + 15
b. 83 = 17h + 15 
    -15           - 15  subtract 15 from both sides 
    68 = 17h
    ------------
         17               divide both sides by 17
      4=h  
  They cleaned the house for 4 hours
c. C = 20x
to do this last part, you would put both equations into the calculator under y=, then look at the table to determine when the price is the same. According to the calculator, the price is the same at 5 hours
