Question

ABC and XYZ are similar. Find the missing side length.

Answer 1

Answer:

56

Step-by-step explanation:

The easiest way to solve this is by cross multiplying. We can make an equation to find the answer of this by simply taking a side from each triangle and then the variable and equal side on the other triangle, shown below.

$let \: \: ? = x$

$\frac{7}{49} = \frac{8}{x}$

Now we solve with cross multiplication

$7 x = 392 \\ x = 56$

Now we know the mystery number is 56
