Question

Triangle XYZ is a scale drawing of triangle ABC.
Triangle ABC has side lengths 3, 4, & 5.
Triangle XYZ has corresponding side lengths x, 12, & 15.
What is the value of x?

Answer 1

Answer:

x = 9

Step-by-step explanation:

∆ABC is similar to ∆XYZ

Therefore:

$\frac{AB}{XY} = \frac{BC}{YZ}$

AB = 4

XY = 12

BC = 3

YZ = x

Plug in the values

$\frac{4}{12} = \frac{3}{x}$

Cross multiply

4x = 36

Divide both sides by 4

x = 9
