ADHE - ADGF below. Find the value of 'x'.<br> X<br> H н<br> E<br> 8<br> 2.<br> 12
Vlad1618 [11]

Given:

\Delta DHE\sim \Delta DGF

To find:

The value of x.

Solution:

We know that, corresponding sides of similar triangles are proportional.

Since,\Delta DHE\sim \Delta DGF, therefore

\dfrac{HE}{GF}=\dfrac{DE}{DF}

On substituting the values from the figure, we get

\dfrac{8}{12}=\dfrac{x}{x+2}

\dfrac{2}{3}=\dfrac{x}{x+2}

On cross multiplication, we get

2(x+2)=3x

2x+4=3x

4=3x-2x

4=x

Therefore, the value of x is 4.

Help pleaseeeeee thanks i hope u have a good day
VikaD [51]

Answer:

12825$

Step-by-step explanation:

1 yard = 3 ft

we can convert each of the lengths from ft to yards

240 ft = 80 yards

285 ft = 95 yards

450 ft = 150 yards

150+150+95+80 = 475 yards

1 yard of fencing costs 27$ so we are going to multiply that by the total yards

475*27=12825$
