Answer:
x = 3
Step-by-step explanation:
We can solve this by using ratios of similar triangles
3 x
------ = ------------
3+9 12
3 x
------ = ------------
12 12
x must equal 3 to keep the ratios the same
The answer would be 10.19m. If you want to round it of to a less precise
measurement it would be 10 m.
X=14
Step by Step
x+10=2x-4
-x. -x
10=x-4
+4. +4
x=14
3/4 because if you make it smaller you would get that
