Use the figure to find the length HJ. Assume △DEF ≅ △GHJ. *I GOT 30*

Yes, HJ = 30 ft.

It tells us that triangle DEF = triangle GHJ.

By seeing this we know without looking at the triangles that EF is going to be the same as HJ because when they say a figure is the same as another and list the letters such as 'DEF' and 'GHJ' they will list them in the same order.

So

'DEF' = 'GHJ' we get:

'DE' = 'GH'

'EF' = 'HJ'

And we can do the last and first letters:

'FD' = 'JG'

And since we know 'EF' = 'HJ' and that they already told us 'EF' was 30, we know HJ will be 30.

In 3-4 sentences, describe how you would find a line parallel to the line 2x + 5y = 15 that goes through the point (-10, 1). Be
larisa86 [58]

the parallel line is 2x+5y+15=0.

Step-by-step explanation:

ok I hope it will work

soo,

Solution

given,

given parallel line 2x+5y=15

which goes through the point (-10,1)

now,

let 2x+5y=15 be equation no.1

then the line which is parallel to the equation 1st

2 x+5y+k = 0 let it be equation no.2

now the equation no.2 passes through the point (-10,1)

or, 2x+5y+k =0

or, 2*-10+5*1+k= 0

or, -20+5+k= 0

or, -15+k= 0

or, k= 15

putting the value of k in equation no.2 we get,

or, 2x+5y+k=0

or, 2x+5y+15=0

which is a required line.
