A service station will be built in the highway, and a road will connect it with cray. How long will the new road be?
abruzzese [7]

Answer: 24 mi

Step-by-step explanation:

Let the points A, B, C and S represent Alba, Blare, Cray and Service station respectively,

Then According to the question,

We have to find out the line segment CS = x = ?

Now, In the triangles ACB and CSB,

\angle ACB\cong \angle CSB     ( Right angles )

\angle ABC\cong \angle CBS      ( Reflexive angles )

Thus, by AA similarity postulate,

\triangle ACB\sim\triangle CSB

By the property of similar triangles,

\frac{AB}{CB}=\frac{AC}{CS}

\implies \frac{50}{30}=\frac{40}{x}

\implies 50x=30\times 40

\implies 50x = 1200

\implies x =24

Thus, the length of the new road = 24 miles
