Mathematics
1 answer:
KonstantinChe [14]3 years ago
7 0

Answer:

x = 6

Step-by-step explanation:

From the given picture,

ΔABC and ΔADE are the similar triangles.

By the property of similar triangles,

Corresponding sides of the similar triangles are proportional.

\frac{AB}{AD}=\frac{AC}{AE}

\frac{x+18}{x}=\frac{28}{(28-21)}

7(x + 18) = 28x

7x + 7×18 = 28x

28x - 7x = 126

21x = 126

x = \frac{126}{21}

x = 6
