PLEASE PLEASE PLEASE HELP ME

Answer 1

We get the value of x: x= 2

Explanation:

Since the triangles are similar, the ratios of the lengths of corresponding sides are same.

We can use proportions to find the value of x

The proportion will be:

`(BD)/(DA)=(BE)/(EC)`

Now putting there values we can find value of x

We have:

BD = 6, DA = 4, BE = x+1, EC =x

Putting values

`(BD)/(DA)=(BE)/(EC)\\(6)/(4)=(x+1)/(x) \\Cross\:Multiply\\6x=4(x+1)\\6x=4x+4\\6x-4x=4x+4-4x\\2x=4\\x=(4)/(2)\\x=2`

So, we get the value of x: x= 2
