Answer:
- x = 2, y = 4.47, z = 2.24
Step-by-step explanation:
As per diagram we see similar triangles:
The ratio of corresponding sides:
- AD/DC = DC/DB
- 1/x = x/ 4
- x² = 4
- x = 2
Use Pythagorean to find the values of y and z:
- z = [tex]\sqrt{1^2+2^2}[/tex] = [tex]\sqrt{5}[/tex] = 2.24
- y = [tex]\sqrt{2^2+4^2}[/tex] = [tex]\sqrt{20}[/tex] = 4.47
