Question

Can someone help me?
Find the length of IJ

Answer 1

10

Explanation:

Seeing the given information, it looks like HI + IJ = HJ

`2x + 4x - 10 = 4x`

Combining like terms

`6x - 10 = 4x`

Lastly we can subtract 6X

`- 10 = - 2x`

We can take the negatives off both sides then divide by 2, this gets rid of the negatives and gets x alone

`x = 5`

Now that IJ is 4X - 10, we can plug in 5

`4(5) - 10 = 10`
