Will give brainliest to first correct answer! find missing length

6

Step-by-step explanation:

They are similar triangles so they have proportionality

For the small triangle the side is 2 and the hypoteneuse is 4, for the large triangle the side is 5 so the entire hypoteneuse is 10. 10-4 = 6 which is the missing side

x=5

Step-by-step explanation:

4x+5=3x+10

All x values must go on the right so subtract 3x from both sides

4x+5=3x+10

-3x -3x

which gets you

x+5=10

Now subtract 5 from both sides to get the value of x

x+5=10

-5 -5

And you get

x=5
