Question

The following triangles are similar. Which of the properties could be used to solve x:

Answer 1

if the triangles are similar , then ,

The small trapezoid is a scaled-down version of the large trapezoid, but is also a mirror image.

So the side x corresponds to the length 45 in the larger trapezoid.

`45 = 2x + 4 \\ 2x = 45 - 4 \\ x = (41)/(2) \\ x = 20.5`
