Answer:
The value of x in the figure is 3.5
Explanation:
When we look at the figure, we see that AB and BC, are connected, to make a longer side of a triangle. We can also see that BC is dilated from AB. When dilating, we multiply or divide by a number, to get the extended or shortened length. (Just keep multiplication and division in mind) To get x, we can do the same that we did to get 2, from 4. From AB to BC it goes from 4 to 2.
To get 2 from 4, you must divide 4 by 2. So when we do the same thing to 7, we should get x.
7 / 2 = 3.5
The value of x in the figure is 3.5
