Answer:
The answer to your question is the letter B. x = 30
Step-by-step explanation:
Data
Find x
Process
To solve this problem use proportions. Compare the small triangle and the large triangle.
1) For the small triangle
x/ (24 - 4) = x/20
2) For the large triangle
(x + 6) / 24
3.- Equal both expressions
x/20 = (x + 6)/24
-Solve for x
24x = 20(x + 6)
-Expand
24x = 20x + 120
-Simplify like terms
24x - 20x = 120
4x = 120
-Result
x = 120/4
x = 30
