Answer:
x=20
Step-by-step explanation:
We can use similar triangle to find x. Put the smaller triangle over the larger triangle.
11 10
-------- = ----------
121+11 10 +5x+10
Combine like terms
11 10
-------- = ----------
132 20+5x
Using cross products
11 (20+5x) = 132*10
Distribute
220 +55x = 1320
Subtract 220 from each side
220-220 +55x = 1320-220
55x = 1100
Divide by 55
55x/55= 1100/55
x =20
