Question

How do I find X in this problem

Answer 1

You know that BC is congruent to x so you need to solve for x using the ratio:

`(12)/(24)=(x)/(BC)`

So then we need to find BC.

We know:

`A=(base * height)/(2)`

`28=(BC * 7)/(2)`
Therefore BC =8

Then:

`(12)/(24)=(x)/(8)`

`x=8 * (12)/(24) = 4`
