A ladder reaches 5 m up a wall. The angle of elevation from the ground to the ladder is 72º. Find the length of the ladder. Round your answer to the nearest tenth of a metre. Draw a diagram and show your work.

5.78

Step-by-step explanation:

Using sin Ф

Where Ф=72°. P = 5m

H = length of  ladder

⇒sin72=

⇒m=

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
