Answer:
x =20
Step-by-step explanation:
We can use similar triangles and proportions to solve. Take the smaller triangle side on top and the larger triangle side on the bottom.
11 10
---------- = --------------
11+121 10 +5x+10
Combine like terms
11 10
---------- = --------------
132 5x+20
Using cross products
11*(5x+20) = 10*132
55x+220 = 1320
Subtract 220 from each side
55x+220-220 = 1320-220
55x = 1100
Divide by 55
55x/55= 1100/55
x =20
multiply 4 by the cos(45)
4 x cos(45) = 2sqrt(2) approximately 2.828cm
so depending how you are supposed to answer, either 2 sqrt(2) or approximately 2.83 cm
