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.

You start at (1, 0). You move up 4 units and down 2 units. Where do you end?
melisa1 [442]

Answer:

(1, 2)

Step-by-step explanation:

You are moving up 4 units, so that means you need to add to the y coordinate, which is 0.  0 + 4 = 4

The new coordinate is (1, 4)

Now you move down 2 units, that means you need to subtract from the y coordinate, which is now 4. 4 - 2 = 2

You will end at (1, 2)
