Show Answer Key & Explanations Step-by-step solution for: Scale Drawings - Find the Missing Side in Similar Figures

▼

- The two triangles are similar, meaning their corresponding sides are in proportion.
- The side of 3 cm in the smaller triangle corresponds to the side of x cm in the larger triangle.
- The side of 4 cm in the smaller triangle corresponds to the side of 8 cm in the larger triangle.
- The side of 5 cm in the smaller triangle corresponds to the side of 10 cm in the larger triangle.
- To find x, set up a proportion using corresponding sides: 3/x = 4/8.
- Simplify the right side: 4/8 = 1/2.
- So, 3/x = 1/2.
- Cross-multiply: 1 * x = 3 * 2.
- Therefore, x = 6.
