Pierre stands on level ground at the point P, 5 metres from O.
GenaCL600 [577]
So hmm notice the picture below

thus    \bf \cfrac{4.24}{x}=\cfrac{2x+5}{2x}\implies 8.48x=2x^2+5x\implies 8.48x-5x=2x^2
\\\\\\
3.48x=2x^2\implies 0=2x^2-3.48x\implies 0=x(2x-3.48)
\\\\\\

\begin{cases}
0=x\\
----------\\
0=2x-3.48\\
3.48=2x\\\\
\cfrac{3.48}{2}=x\\\\
1.74=x
\end{cases}

so, is clearly not 0, so it has to be 1.74

20 Solve for X.<br> 1<br> 80°<br> 13x - 4
Vikki [24]

Answer:

13x - 4 + 80 = 180⁰ (Sum of co interiar angles)

13x +76 = 180⁰

13x = 180⁰ - 76⁰

x = 104/13

x = 8

Given:<br> m∠LON=77 °<br> m∠LOM=9x+44 °<br> m∠MON=6x+3 °<br><br> Find ∠MON
NISA [10]

Answer:

m\angle MON=15^o

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m\angle LON=m\angle LOM+m\angle MON ---> by addition angle postulate

substitute the given values

77^o=(9x+44)^o+(6x+3)^o

solve for x    

77=(15x+47)

15x=77-47                                

15x=30\\x=2                                                

<em>Find the measure of angle MON   </em>

m\angle MON=(6x+3)^o      

substitute the value of x        

m\angle MON=(6(2)+3)=15^o

George and carmen went on a bicycle trip. they took a bus to their starting piont, and then biked the rest. they traveled 275 ki
rodikova [14]
We need to do a system of equations here.

x + y = 275 (if you travel <em>x</em> km by bike and <em>y </em>km by bus, then you travel 275 km as given in the problem)
y = x + 55 (the problem stated that they were bussed (y) the amount they biked plus 55 more km (x + 55))

The second equation is already solved for y. So, we can plug it in to the first equation.

x + (x + 55) = 275
2x + 55 = 275 [combine x terms]
2x = 220 [subtract 55 from both sides]
x = 110 [divide by 2 to isolate x and solve for it]

Now we know that x is 110, the distance they traveled by bike.
And that's what we needed to answer the problem!
