This is my thinking;

To convert meters to kilometers, in decimals, its 0.001. So converting that into kilometers, that would be 0.057

You need to convert m to km. There are 1000m per km, so divide your m by 1000. 56m=0.056km

Answer:

Step-by-step explanation:

m∠D = 90° - 51° = 39°

sin E = $\frac{DE}{DF}$ ⇒ DE = DF × sin E

DE = 18 sin51° ≈ 14.0 ft.

cos E = $\frac{EF}{DF}$ ⇒ EF = DF × cos E

EF = 18 × cos51° ≈ 11.3 ft.

The markup is 150%

126/84= 1.5
1.5 x 100 = 150%
