Show Answer Key & Explanations Step-by-step solution for: Properties of Similar Triangles - Algebra Review (Video)

▼

- The two triangles, ABC and DEF, are similar.
- Corresponding sides of similar triangles are proportional.
- Side AB corresponds to side DE, and side BC corresponds to side EF.
- Set up the proportion: AB/DE = BC/EF.
- Substitute the known values: 13/27 = 21/X.
- Cross-multiply to solve for X: 13 * X = 27 * 21.
- Calculate the product: 13X = 567.
- Divide both sides by 13: X = 567 / 13.
- Simplify the fraction: X = 43.615... (approximately 43.62).

Parent Tip: Review the logic above to help your child master the concept of similar triangles.
