Given that triangles ABC and DEF are similar, the value of x is: D. 6⅔.
What are Similar Triangles?
If two triangles are similar, it means they have the same shape but different sides, and therefore, the ratio of their corresponding sides are equal.
Thus:
BC/EF = AC/DF
- Substitute
8/2x = 3/5
- Cross multiply
40 = 6x
- Divide both sides by 6
x = 6⅔.
In summary, given that triangles ABC and DEF are similar, the value of x is: D. 6⅔.
