Medians $\overline{dp}$ and $\overline{eq}$ of $\triangle def$ are perpendicular. if $dp= 18$ and $eq = 24$, then what is ${de}$
monitta
Denote by M the point of  intersection of the medians. 
Denote also the distance DM by x and the distance QM by y. 
From the median properties of triangles we know that
 y=\frac{1}{3}\timesFQ=\frac{1}{3}\times24=8
Also, 
x=\frac{2}{3}\times DP=\frac{2}{3}\times 18=12
Since the medians are perpendicular, we deduce that:
x^2+y^2=DQ^2\iff DQ=\sqrt{8^2+12^2}=14.4
Then, since DE=2\times DQ\text{ then }DE=2\times 14.4=28.8

Liono4ka [1.6K]

Answer:

The ruins of the day

Painted with a scar

And the more I straighten out

The less it wants to try

The feelings start to rot

One wink at a time

Oh oh

Forgiving who you are

For what you stand to gain

Just know that if you hide

It doesn't go away

When you get out of bed

Don't end up stranded

Horrified with each stone

On the stage

My little dark age

Picking through the cards

Knowing what's nearby

The carvings on the face

Say they find it hard

And the engine's failed again

All limits of disguise

The humor's not the same

Coming from denial

Oh oh

I grieve in stereo

The stereo sounds strange

I know that if you hide

It doesn't go away

If you get out of bed

And find me standing all alone

Open-eyed

Burn the page

My little dark age

I grieve in stereo

The stereo sounds strange

You know that if it hides

It doesn't go away

If I get out of bed

You'll see me standing all alone

Horrified

On the stage

My little dark age

Giddy with delight

Seeing what's to come

The image of the dead

Dead ends in my mind

Policemen swear to God

Love's seeping from the guns

I know my friends and I

Would probably turn and run

If you get out of bed

Come find us heading for the bridge

Bring a stone

All the rage

My little dark age

I grieve in stereo

The stereo sounds strange

I know that if you hide

It doesn't go away

If you get out of bed

And find me standing all alone

Open-eyed

Burn the page

My little dark age

All alone

Open-eyed

Burn the page

My little dark age
