Ответ:
28.3
Step-by-step explanation:
The triangles are similar, so we can use the scale factor to calculate the value of x:
12/20 = 3/5 is the scale factor
17/x = 3/5 cross multiply expressions
85 = 3x divide both sides by 3
28.3 = x approximately
Ответ:
3 (x -2) = 22 -x
4x -6 = 22
4x = 28
x = 7
Only one solution exists
