The Traingle XYZ and ACB are similar triangles. tanX = tanA = 5 over 2 and 5 tenths,

AC = 2 * XY; CB = 2 * YZ

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Triangle XYZ was dilated by a scale factor of 2 to create triangle ACB, hence XYZ and ACB are similar triangles.

Angles Y and C both measure 90 degrees, and angles A and X are congruent. Hence:

tanX = tanA = 5 over 2 and 5 tenths

AC = 2 * XY; CB = 2 * YZ
