Answer:

x=75

Step-by-step explanation:

$We\ are\ given\ that, \\Angle GFE=105\\We\ observe\ that, \\Angle\ GFE\ and Angle\ EFB\ form\ a\ linear\ pair\ and\ hence,\ are\ supplementary.\\Hence,\\Angle\ GFE\ + Angle\ EFB=180\\Hence,\\105+Angle\ EFB=180\\Angle\ EFB=180-105\\Angle\ EFB=75\\We\ know\ observe\ that\ Angle\ EFB\ and\ Angle\ ABC\ are\ corresponding\ angles\ and\ are\ equal\\Hence,\\Angle\ EFB\ = \ Angle\ ABC\\75=Angle\ ABC\\75=x\\x=75$

ohaa [14]

The equation can be used to find the time in hours, $\dfrac{t}{4}+\dfrac{t}{7}=1$ and the time will be 2.5 hours. So the correct answer is option A.

<h3>What is an equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Layna can paint a 350-square-foot room in 4 hours.It takes Bebe 7 hours to paint the same room.

Let t be the total time taken by both to paint.They are completing 1 job so the equation will be :

$\dfrac{t}{4}+\dfrac{t}{7}=1$

Further solving it we get;

7 t + 4 t = 28

11t = 28

t = 2.5 hours.

Therefore the equation can be used to find the time in hours, $\dfrac{t}{4}+\dfrac{t}{7}=1$ and the time will be 2.5 hours. So the correct answer is option A.
