Question

Find the value of x that makes angle DEF ~ angle XYZ

Answer 1

4

Explanation:

The ratio between the sides on both triangles, 5 and 10 is 2. Meaning each side would be doubled from triangle DEF to XYZ. So it means that side YZ (14) is soluble of what EF (2X-1) is. Half of 14 is 7 meaning that 2X-1=7. When you solve for X, you get 4.
