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

Solve the question given below

tamaranim1 [39]

Answer:

41.04

Step-by-step explanation:

Given

$\sqrt{207936}$ = 456, then

$\sqrt{\frac{207936}{100} }$ = $\sqrt{2079.36}$ = $\frac{456}{10}$ = 45.6

$\sqrt{\frac{207936}{10000} }$ = $\sqrt{20.7936}$ = $\frac{456}{100}$ = 4.56

Thus

$\sqrt{2079.36}$ - $\sqrt{20.7936}$ = 45.6 - 4.56 = 41.04
